IMAGE COMPRESSION

INTRODUCTION:

Digital image compression is a very popular research topic in the field of multimedia processing. Its goal is to store an image in a more compact form, i.e., a representation that requires fewer bits than the original image. It relies on the fact that image information, by its very nature, is not random but exhibits order and has some form of structure. If this order and structure can be extracted, the essence of the information often can be represented and transmitted using less data bits than would be needed for the original. We can then reconstruct the original or a close approximation of it at the receiving end.

Image, video and audio signals can be compressed due to the following reasons:

• Within a single image or a single video frame, there exists significant correlation or redundancy among neighboring samples or pixels. This correlation is referred as spatial correlation or redundancy.

• For data acquired from multiple sensors (such as satellite images), there exists significant correlation or redundancy among samples from these sensors. This correlation or redundancy is called spectral correlation or redundancy.

• For temporal data (such as video sequence), there is significant correlation or redundancy among pixels of successive video frames. This is referred to as temporal correlation or redundancy.


A systematic view of the compression process is depicted in Figure 2.1.



As depicted in Figure 2.1, the source coder performs the compression process by reducing the input image data size to a level that can be supported by the storage or transmission channel. The output bit rate of the encoder is measured in bits per sample or bits per pixel. For image or video data, a pixel is the basic element therefore bits per sample (bps) also referred to as bits per pixel (bpp). The channel coder translates the compressed bit-stream into a signal suitable for either storage or transmission using various methods such as variable length coding, Huffman coding or Arithmetic coding.
In order to reconstruct the image or video data the process is reversed at the decoder. In compression systems, the term ‘compression ratio’ is used to characterize the compression capability of the system.

Compression ratio = Source coder input data size
Source coder output data size

For a still image, size could to the bits needed to represent the entire image. For video, size could refer to the bits needed to represent one frame of video, i.e., one second of video.



4.2 Classifying Compression Schemes

The classification of compression schemes can be done in the following manner.
(a) Lossless vs. Lossy compression: In lossless compression schemes the reconstructed image, after compression, is digitally identical to the original image. However, lossless compression can only achieve a modest amount of compression. On the other hand, lossy schemes are capable of achieving much higher compression but under normal viewing conditions no visible loss is perceived (visually lossless). Some of the lossy compression schemes used include differential pulse code modulation (DPCM), pulse code modulation (PCM), vector quantization (VQ), Transform and Subband coding. An image reconstructed following a lossy compression contains degradation relative to the original. Often this is because the compression scheme also discards non-redundant information.
(b) Predictive vs. Transform coding: In predictive coding, information already sent or available is used to predict other values, and the difference is coded. Since this is done in the image or spatial domain, it is relatively simple to implement and is readily adapted to local image characteristics. The DPCM is one particular example of predictive coding. Transform coding, on the other hand, first transforms the image from its spatial domain representation to a different type of representation using some well-known transforms such as DCT, DWT or Lapped transform, and then codes the transformed values (coefficients). This method provides greater data compression compared to predictive methods as transforms use energy compaction properties to pack an entire image or a video frame into fewer transform coefficients. Most of these coefficients become insignificant after applying quantization, which means less data to be transmitted. In predictive coding, the differences between the original image or video frame samples and the predicted ones remain significant even after applying quantization. This means more data to be transmitted compared to transform coding.


(c) Subband Coding: The fundamental concept behind subband coding is to split the frequency band of a signal (image in our case) in various subbands. To code each subband, we use a coder and bit rate accurately matched to the statistics of the subband.

Electric Discharge in Vacuum

The electric discharge in vacuum results from the neutral atoms, ions and electrons emitted from
the electrodes themselves. Cathode spots are formed depending upon the current flowing. For low
currents a highly mobile cathode spot is formed and for large currents a multiple number of cathode
spots are formed. These spots constitute the main source of vapour in the arc. The processes involved
in drawing the discharge will be due to high electric field between the contacts or resistive heating
produced at the point of operation or a combination of the two. The cathode surfaces, normally, are not
perfectly smooth but have many micro projections. Due to their small area of cross-section, the projec-
tions will suffer explosive evaporation by resistive heating and supply sufficient quantity of vapour for
the arc formation. Since in case of vacuum, the emission occurs only at the cathode spots and not from
the entire surface of the cathode, the vacuum discharge is also known as cold cathode discharge. In
cold cathode the emission of electrons could be due to any of the combinations of the following mecha-
nisms: (i) Field emission; (ii) Thermionic emission; (iii) Field and Thermionic emission; (iv) Second-
ary emission by positive ion bombardment; (v) Secondary emission by photons; and (vi) Pinch effect.
The stability of discharge in vacuum depends upon: (i) the contact material and its vapour pres-
sure, and (ii) circuit parameters such as voltage, current, inductance and capacitance. It has been ob-
served that higher the vapour pressure at low temperature the better is the stability of the discharge.
There are certain metals like Zn, Bi which show these characteristics and are better electrode materials
for vacuum breakers. Besides the vapour pressure, the thermal conductivity of the metal also affects the
current chopping level. A good heat conducting metal will cool its surface faster and hence its elec-
trode surface temperature will fall which will result into reduction in evaporation rate and arc will be
chopped because of insufficient vapour. On the other hand, a bad heat conductor will maintain its
temperature and vaporization for a longer time and the arc will be more stable.
The process of multiplication of charged particles by the process of collision is very small in the
space between the electrode in vacuum, electron avalanche is not possible. If somehow a gas cloud
could be formed in vacuum, the usual kind of breakdown process can take place. This is the line of
action adopted by the researchers to study mechanism of breakdown in vacuum. By finding the way,
gas cloud could be created in a vacuum.

Application of Oil in Power Apparatus

Oil is normally used for providing insulation between the live parts of different phases and between
phases and the grounded enclosure containing the oil and the main parts of the apparatus. Also it
provides cooling effect to the apparatus placed within the enclosure. Besides providing insulation, the
oil helps the C.B. to quench the arc produced between the breaker contacts when they begin to separate
to eliminate the faulted section from the healthy section of the system.

In an oil circuit breaker, the heat of the oil decomposes the oil which boils at 658 K. The gases
liberated are approx. (i) Hydrogen, 70%, (ii) Acetylene, 20%, (iii) Methane, 5% and (iv) Ethane, 5%.
(the abbreviation for these gases could be used as HAME).
The temperature about the arc is too high for the three last-named gases to exist and the arc itself
runs into a mixture of hydrogen, carbon and copper vapour at temperature above 6000 K. The hydrogen
being a diatomic gas gets dissociated into the atomic state which changes the characteristics of the arc
on account of its associated change in its thermal conductivity. The outcome of this is that the discharge
suddenly contracts and acquires an appreciably higher core temperature. In certain cases, the thermal
ionization may be so great that the discharge runs with a lower voltage which may stop the ionization
due to the electric field strength. The transition from the field ionization to thermal ionization is most
marked in hydrogen and, therefore, in oil circuit breakers.
The separation of the C.B. contacts which are carrying current gives rise to an arc without
changing much the current wave form. Initially when the contacts just begin to separate the magnitude
of current is very large but the contact resistance being very small, a small voltage appears across them.
But the distance of separation being very very small, a large voltage gradient is set up which is good
enough to cause ionization of the particles between the contacts. Also it is known that with the copper
contacts which are generally used for the circuit breakers very little thermal ionization can occur at
temperature below the melting point. For effective field emission, the voltage gradient required is 106
V/cm. From this it is clear that the arc is initiated by the field emission rather than the thermal ioniza-
tion. This high voltage gradient exists only for a fraction of a micro-second. But in this short period, a
large number of electrons would have been liberated from the cathode and these electrons while reach-
ing anode, on their way would have collided with the atoms and molecules of the gases. Thus, each
emitted electron tends to create others and these in turn derive energy from the field and multiply. In
short, the work done by the initially-emitted electrons enables the discharge to be maintained. Finally,
if the current is high, the discharge attains the form of an arc having a temperature high enough for
thermal ionization, which results in lower voltage gradient. Thus, an arc is initiated due to field effect
and then maintained due to thermal ionization.

TESTING OF TRANSFORMER OIL

The oil is poured in a container known as test-cell which has internal dimensions of 55 mm × 90 mm
× 100 mm high. The electrodes are polished spheres of 12.7 to 13 mm diameter, preferably of brass,
arranged horizontally with their axis not less than 40 mm above the bottom of the cell. For the test, the distance between the spheres shall be 4 + 0.02 mm. A suitable gauge is used to adjust the gap. While
preparing the oil sample, the test-cell should be thoroughly cleaned and the moisture and suspended
particles should be avoided. Fig. 1.13 shows an experimental set-up for finding out the dielectric strength
of the given sample of oil. The voltmeter is connected on to the primary side of the high voltage
transformer but calibrated on the high voltage side.





The gap between the spheres is adjusted to 4 mm with the help of a gauge and the spheres are
immersed in oil to a depth as mentioned earlier. The voltage is increased gradually and continuously till
a flash over of the gap is seen or the MCB operates. Note down this voltage. This voltage is known as
rapidly-applied voltage. The breakdown of the gap has taken place mainly due to field effect. The
thermal effect is minimal as the time of application is short.
Next bring the voltage back to zero and start with 40% of the rapidly applied voltage and wait
for one minute. See if the gap has broken. If not, increase the voltage everytime by 2.1/2% of the
rapidly applied voltage and wait for one minute till the flash over is seen or the MCB trips. Note down
this voltage.
Start again with zero voltage and increase the voltage to a value just obtained in the previous
step and wait for a minute. It is expected that the breakdown will take place. A few trials around this
point will give us the breakdown value of the dielectric strength. The acceptable value is 30 kV for 4
mm applied for one minute. In fact these days transformer oils with 65 kV for 4 mm 1 minute value are
available. If it is less than 30 kV, the oil should be sent for reconditioning. It is to be noted that if the
electrodes are immersed vertically in the oil, the dielectric strength measured may turn out to be lower
than what we obtained by placing the electrodes in horizontal position which is the normal configuration. It is due to the fact that when oil decomposes carbon particles being lighter rise up and if the
electrodes are in vertical configuration, these will bridge the gap and the breakdown will take place at
a relatively lower value.

Application of Gases in Power System

The gases find wide application in power system to provide insulation to various equipments and
substations. The gases are also used in circuit breakers for arc interruption besides providing insulation
between breaker contacts and from contact to the enclosure used for contacts. The various gases used
are (i) air (ii) oxygen (iii) hydrogen (iv) nitrogen (v) CO2 and (vi) electronegative gases like sulphur
hexafluoride, arcton etc.
The various properties required for providing insulation and arc interruption are:
(i) High dielectric strength.
(ii) Thermal and chemical stability.
(iii) Non-inflammability.
(iv) High thermal conductivity. This assists cooling of current carrying conductors immersed in
the gas and also assists the arc-extinction process.
(v) Arc extinguishing ability. It should have a low dissociation temperature, a short thermal
time constant (ratio of energy contained in an arc column at any instant to the rate of energy dissipation
at the same instant) and should not produce conducting products such as carbon during arcing.
(vi) Commercial availability at moderate cost. Of the simple gases air is the cheapest and most
widely used for circuit breaking. Hydrogen has better arc extinguishing property but it has lower di-
electric strength as compared with air. Also if hydrogen is contaminated with air, it forms an explosive
mixture. Nitrogen has similar properties as air, CO2 has almost the same dielectric strength as air but is
a better arc extinguishing medium at moderate currents. Oxygen is a good extinguishing medium but is
chemically active. SF6 has outstanding arc-quenching properties and good dielectric strength. Of all
these gases, SF6 and air are used in commercial gas blast circuit breakers.
Air at atmospheric pressure is ‘free’ but dry air costs a lot when stored at say 75 atmosphere.
The compressed air supply system is a vital part of an air blast C.B. Moisture from the air is removed by
refrigeration, by drying agents or by storing at several times the working pressure and then expanding
it to the working pressure for use in the C.B. The relative cost of storing the air reduces with increase in
pressure. If the air to be used by the breaker is at 35 kg/cm2 it is common to store it at 210 kg/cm2.
Air has an advantage over the electronegative gases in that air can be compressed to extremely
high pressures at room temperature and then its dielectric strength even exceeds that of these gases.
The SF6 gas is toxic and its release in the form of leakage causes environmental problems.
Therefore, the electrical industry has been looking for an alternative gas or a mixture of SF6 with some
other gas as an insulating and arc interrupting medium. It has been observed that a suitable mixture of
SF6 with N2 is a good replacement for SF6. This mixture is not only finding acceptability for providing
insulation e.g., gas insulated substation and other equipments, it is able to quench high current magni-
tude arcs. The mixture is not only cost effective, it is less sensitive to find non-uniformities present
within the equipment. Electric power industry is trying to find optimum SF6 to N2 mixture ratio for
various components of the system viz., GIS, C.B., capacitors, CT, PT and cables. A ratio 70% of SF6
and 30% of N2 is found to be optimum for circuit breaking. With this ratio, the C.B. has higher recovery
rate than pure SF6 at the same partial pressure. The future of using SF6 with N2 or He for providing
insulation and arc interruption is quite bright.

MECHANISM OF BREAKDOWN OF GASES

At normal temperature and pressure, the gases are excellent insulators. The current conduction is of the
order of 10–10 A/cm2. This current conduction results from the ionisation of air by the cosmic radiation
and the radioactive substances present in the atmosphere and the earth. At higher fields, charged parti-
cles may gain sufficient energy between collision to cause ionisation on impact with neutral molecules.
It is known that during an elastic collision, an electron loses little energy and rapidly builds up its
kinetic energy which is supplied by an external electric field. On the other hand, during elastic colli-
sion, a large part of the kinetic energy is transformed into potential energy by ionising the molecule
struck by the electron. Ionisation by electron impact under strong electric field is the most important
process leading to breakdown of gases.
This ionisation by radiation or photons involves the interaction of radiation with matter.
Photoionisation occurs when the amount of radiation energy absorbed by an atom or molecule exceeds
its ionisation energy and is represented as A + hν → A+ + e where A represents a neutral atom or molecule in the gas and hν the photon energy. Photoionization is a secondary ionization process and is
essential in the streamer breakdown mechanism and in some corona discharges. If the photon energy is
less than the ionization energy, it may still be absorbed thus raising the atom to a higher energy level.
This is known as photoexcitation.
The life time of certain elements in some of the excited electronic states extends to seconds.
These are known as metastable states and these atoms are known as metastables. Metastables have a
relatively high potential energy and are, therefore, able to ionize neutral particles. Let A be the atom to
be ionized and Bm the metastable, when Bm collides with A, ionization may take place according to the
reaction.
A + Bm → A+ + B + e
Ionization by metastable interactions comes into operation long after excitation and it has been
shown that these reactions are responsible for long-time lags observed in some gases.
Thermal Ionisation: The term thermal ionisation in general applies to the ionizing actions of
molecular collisions, radiation and electron collisions occurring in gases at high temperatures. When a
gas is heated to high temperature, some of the gas molecules acquire high kinetic energy and these
particles after collision with neutral particles ionize them and release electrons. These electrons and
other high-velocity molecules in turn collide with other particles and release more electrons. Thus, the
gas gets ionized. In this process, some of the electrons may recombine with positive ions resulting into
neutral molecule. Therefore, a situation is reached when under thermodynamic equilibrium condition
the rate of new ion formation must be equal to the rate of recombination. Using this assumption, Saha
derived an expression for the degree of ionization β in terms of the gas pressure and absolute tempera-
ture as follows:
[β2/1 − β2]=[1 ( 2πm(e )^ 3/ 2 ( KT ) 5 / 2 e ^− W / KT]/ph


where p is the pressure in Torr, Wi the ionization energy of the gas, K the Boltzmann’s constant, β the
ratio ni/n and ni the number of ionized particles of total n particles. Since β depends upon the tempera-
ture it is clear that the degree of ionization is negligible at room temperature. Also, if we substitute the
values of p, Wi, K and T, it can be shown that thermal ionization of gas becomes significant only if
temperature exceeds 1000° K.

Silence modelling in transducer

. General practice
Silence models are necessary in ASR to accommodate periods
of silence at the beginning and end of utterances, and between
words. Typically, any sound not included in the phone set of the
decoder is included in the definition of silence; it might better
be termed non-speech or noise. There may also be an element
of garbage modelling in a silence model. The key, however,
is the way the model is used. Silence is (trivially) placed at
the beginning and end of the grammar, and can be included in
G. Silence is also placed between words; the most convenient
way to enable this is to duplicate lexicon entries such that each
pronunciation has one unmodified phonetic spelling, and one
either beginning or ending in silence.
The HTK system, as described by Young et al. [3], advocates
the use of two silence models:
1. A silence model, sil, with the same structure as the
other phonetic models, and contextually a monophone.
i.e., silence acts as a context, but is context independent.
2. A short pause model, sp, that is essentially tied to the
silence model, but is context free, and has a ‘skip’ transition
that optionally omits any emitting states.
The silence model is used at the beginning and end of an utterance,
or when prescribed in the grammar by a specific token.
The short pause model is used in the lexicon at the end of every
word to allow optional silence states that do not break context.
The use of the short pause model at the end of each word
was revised by Hain et al. [6] to advocate the use of both short
pause and silence at the word ends. This gives the option of
either breaking context or not between words at decode time,
and leads to a small improvement in recognition accuracy. In
fact, Hain et al. distinguish the case where neither silence nor
short pause are used, although this is included in the short pause
skip structure.
2.2. Silence inWFSTs
Silence in WFSTs is discussed briefly by Allauzen et al. [7].
In that paper, silence is represented as a loop that can be placed
at the end of each word in the lexicon. Further, it is stressed
that the loop must be weighted to allow weight pushing in the
composition process. The silence class transducer, figure 4 in
[7], bears a close similarity to the short pause phone of the HTK
system. Both allow zero or more instances of a silence state
after each word, where the transition probabilities are learned
from data.
It follows that including silence in the grammar is often not
feasible as the grammar does not generally contain probability
information for silence. However, including a short pause
model after each word in the lexicon implements both the HTK
short pause model as described, and has the same effect as the
AT&T silence transducer. A silence model can be trivially included
after each word in the lexicon in the same manner as the
short pause model.
2.3. Juicer
For the common case of a three emitting state model, an HTK
HMM actually has five states with the first and last being nonemitting.
The short pause model is normally implemented with
a ‘skip’ transition from the first state to the last, allowing it to be
skipped completely. Juicer was designed to be compatible with
HTK style HMMs. However, for simplicity in the decoder, skip
transitions were not considered. Rather, a skip transition could
easily be included in the WFST at the lexicon level.
The AMI system uses the double silence method of Hain
et al. [6]. This was implemented in Juicer as shown in figure
1. The example is for just the word ‘NO’ in the lexicon WFST
L. Notice that the other symbols are standard in the WFST
literature: The symbol refers to an epsilon transition
and #1 is an auxiliary symbol to distinguish otherwise identical
pronunciations.

Silence Models in Weighted Finite-State Transducers

Abstract
We investigate the effects of different silence modelling
strategies in Weighted Finite-State Transducers for Automatic
Speech Recognition. We show that the choice of silence models,
and the way they are included in the transducer, can have
a significant effect on the size of the resulting transducer; we
present a means to prevent particularly large silence overheads.
Our conclusions include that context-free silence modelling fits
well with transducer based grammars, whereas modelling silence
as a monophone and a context has larger overheads.

Introduction
A recent trend in Automatic Speech Recognition (ASR) research
has been to use decoders with precompiled grammars.
Such grammars are generated using the Weighted Finite-State
Transducer (WFST) methodology of Mohri et al. [1]. The advantage
over traditional decoders is that various optimisations
such as language model lookahead, prefixing and suffixing are
subsumed into generic WFST operations such as composition
and determinisation. This in turn can vastly reduce the complexity
required in the decoder itself. The composition process
typically deals with four transducers: A grammar, G, a lexicon,
L, a context dependency graph, C and a Hidden Markov Model
(HMM), H. The four transducers are composed into a single
transducer in an operation that is normally writtenH.C.L.G.
The decoder then (typically) only has to maximise the likelihood
of a path through the combined transducer given acoustic
observation likelihoods.
Juicer [2] is a WFST decoder developed at IDIAP. It is designed
to handle both HMMs typically produced by HTK [3],
and HMM/MLP hybrids where the observations are posterior
probabilities. Juicer uses a type of WFST denoted C . L . G;
that is, the HMMgraph is handled in the decoder, and theWFST
transduces from words to models (rather than to states or PDFs,
as would a H . C . L . G transducer). This type of transducer
is described by Mohri et al. [4], where the authors state that
the final transducer should have around 2.1 times the number of
arcs as G for a bigram grammar; 2.5 times for a trigram.
This paper is motivated by our work on using Juicer in
the AMI (Augmented Multi-party Interaction) system [5]. The
AMI language model is typically a 50,000 word trigram, pruned
to fit speed and memory constraints. In building even heavily
pruned language model WFSTs, however, we were finding
that the process was using several gigabytes of core memory
and producingWFSTs significantly larger than predicted in [4].
Although some of the difficulties could be alleviated by careful
tuning of the composition process, one significant problem
turned out to be to do with silence modelling. Our investigation
followed an initial observation that removal of the silence models
resulted in almost a 50% reduction in the size of the final
transducer.
In this paper, we discuss silence modelling in general and
in the context of WFSTs. We show how different silence modelling
strategies affect the size of the resulting WFSTs, and discuss
implications for the decoder, and for the ASR system in
general.

Long-term financial options

What are various Long-term financial options available for investment?

Post Office Savings Schemes, Public Provident Fund, Company Fixed Deposits, Bonds and Debentures, Mutual Funds etc.

Post Office Savings: Post Office Monthly Income Scheme is a low risk saving instrument, which can be availed through any post office. It provides an interest rate of 8% per annum, which is paid monthly. Minimum amount, which can be invested, is Rs. 1,000/- and additional investment in multiplesof 1,000/-.Maximum amount is Rs. 3,00,000/- (if Single) or Rs. 6,00,000/- (if held Jointly) during a year. It has a maturity period of 6 years. A bonus of 10% is paid at the time of maturity. Premature withdrawal is permitted if deposit is more than one year old. A deduction of 5% is levied from the principal amount if withdrawn prematurely; the 10% bonus is also denied.

Public Provident Fund: A long term savings instrument with a maturity of 15 years and interest payable at 8% per annum compounded annually. A PPF account can be opened through a nationalized bank at anytime during the year and is open all through the year for depositing money. Tax benefits can be availed for the amount invested and interest accrued is tax-free. A withdrawal is permissible every year from the seventh financial year of the date of opening of the account and the amount of withdrawal will be limited to 50% of the balance at credit at the end of the 4th year immediately preceding the year in which the amount is withdrawn or at the end of the preceding year whichever is lower the amount of loan if any.

Company Fixed Deposits: These are short-term (six months) to medium-term (three to five years) borrowings by companies at a fixed rate of interest which is payable monthly, quarterly, semi-annually or annually. They can also be cumulative fixed deposits where the entire principal alongwith the interest is paid at the end of the loan period. The rate of interest varies between 6-9% per annum for company FDs. The interest received is after deduction of taxes.

Bonds : It is a fixed income (debt) instrument issued for a period of
more than one year with the purpose of raising capital. The central or state government, corporations and similar institutions sell bonds. A bond is generally a promise to repay the principal along with a fixed rate of interest on a specified date, called the Maturity Date.

Mutual Funds: These are funds operated by an investment company which raises money from the public and invests in a group of assets
(shares, debentures etc.), in accordance with a stated set of objectives. It is a substitute for those who are unable to invest directly in equities or debt because of resource, time or knowledge constraints. Benefits include professional money management, buying in small amounts and diversification. Mutual fund units are issued and redeemed by the Fund Management Company based on the fund's net asset value (NAV), which is determined at the end of each trading session. NAV is calculated as the value of all the shares held by the fund, minus expenses, divided by the number of units issued. Mutual Funds are usually long term investment vehicle though there some categories of mutual funds, such as money market mutual funds which are short term instruments.
