ABSTRACT
Multimedia data compression is a challenging situation for compression technique, due to the possibility of loss
of data as well as it require large amount of storage place. The minimization of storage place and proper
transmission of these data need compression. In this dissertation we proposed a block based DWT image
compression technique using genetic algorithm and HCC code matrix. The HCC code matrix compressed into
two different set redundant and non-redundant which generate similar pattern of block coefficient. The similar
block coefficient generated by particle of swarm optimization. The process of particle of swarm optimization is
select for the optimal block of DWT transform function. For the experimental purpose we used some standard
image such as Lena, Barbara and cameraman image. The size of resolution of this image is 256*256. The source
of image is Google.
Keywords - DWT, HCC, Transform function, HVS.
I. INTRODUCTION
The computer is becoming more and more
powerful day by day. As a result, the use of digital
images is increasing rapidly. Along with this
increasing use of digital images comes the serious
issue of storing and transferring the huge volume of
data representing the images because the
uncompressed multimedia (graphics, audio and
video) data requires considerable storage capacity
and transmission bandwidth. Though there is a rapid
progress in mass storage density, speed of the
processor and the performance of the digital
communication systems, the demand for data storage
capacity and data transmission bandwidth continues
to exceed the capabilities of on hand technologies
[13]. Besides, the latest growth of data intensive
multimedia based web applications has put much
pressure on the researchers to find the way of using
the images in the web applications more effectively.
Internet teleconferencing, High Definition Television
(HDTV), satellite communications and digital storage
of movies are not feasible without a high degree of
compression. Compression-then-Encryption (CTE)
paradigm meets the requirements in many secure
transmission scenarios, the order of applying the
compression and encryption needs to be reversed in
some other situations. As the content owner, Alice is
always interested in protecting the privacy of the
image data through encryption. Nevertheless, Alice
has no incentive to compress her data, and hence, will
not use her limited computational resources to run a
compression algorithm before encrypting the data.
This is especially true when Alice uses a resource-
deprived mobile device. To limit the effects of data
loss that may occur on the communications channel,
the wavelet transformed image data are partitioned
into segments, each loosely corresponding to a
different region of the image. Each segment is
compressed independently, so that the effects of data
loss or corruption are limited to the affected segment.
The image is actually a kind of redundant data i.e. it
contains the same information from certain
perspective of view [6]. By using data compression
techniques, it is possible to remove some of the
redundant information contained in images. Image
compression minimizes the size in bytes of a graphics
file without degrading the quality of the image to an
unacceptable level. The reduction in file size allows
more images to be stored in a certain amount of disk
or memory space. It also reduces the time necessary
for images to be sent over the Internet or downloaded
from web pages. Two elementary components of
compression are redundancy and irrelevancy
reduction. Redundancy reduction aims at removing
duplication from the signal source image. Irrelevancy
reduction omits parts of the signal that is not noticed
by the signal receiver, namely the Human Visual
System (HVS). Image compression is an application
of data compression that encodes the original image
with few bits. The objective of image compression is
to reduce the redundancy of the image and to store or
transmit data in an efficient form. Section-II gives the
information of about introduction of image
compression. In section III discuss the method of
image compression. In section IV discuss the

II. PRINCIPALS OF IMAGE
COMPRESSION
Communication systems now a day‟s greatly rely
on image compression algorithms to send images and
video from one place to another. Every day, a
massive amount of information is stored, processed,
and transmitted digitally. The arrival of the biometric
identity concept demands that governments around
the world keep profiles of their citizens, and for
businesses to keep profiles of their customers and
produce the information over the internet. Image
compression addresses the problem of pressing large
amounts of digital information into smaller packets
(by reducing the size of image and data files) that can
be moved quickly along an electronic medium before
communication can take place effectively.
Compressing images results in reduced transmission
time and decrease storage requirements [4]. Whereas
uncompressed multimedia files require considerable
storage capacity and transmission bandwidth. The
good compression system should be able to
reconstruct the compressed image source or an
approximation of it with good quality. It is an
important branch of image processing that is still a
very active research field and attractive to industry.
Basic components of a data compression system are
illustrated in below Figure. There are two different
encoding systems in operation within the
compression system, the predictive coding, and the
transform coding. Predictive coding works directly
on the input image pixel values as they read into the
system; the spatial or space domain encoder also has
the capacity to efficiently expect the value of the
present sample from the value of those which have
been processed previously. So this type of coding has
to search for the relationship that governs the tile
pixels and make a decision for the best way of
operating them before the coding process start.
Transform coding on the other hand uses frequency
domain, in which the encoding system initially
converting the pixels in space domain into frequency
domain via transformation function. Thus producing
a set of spectral coefficients which are then suitably
coded and transmitted. The background research of
this chapter will focus on the transform coding since
the Bin DCT algorithm by itself is also transforms the
row image in space domain into spatial frequency
domain. The decoder on the other side must perform
an inverse transform before the reconstructed image
can be displayed. The coding technique implemented
in this project is the transform coding using
multiplier-less approximation of the DCT algorithms.
Figure 1: Basic Data Compression System.
Feature extraction process play important role in
face detection and pattern detection system based
authentication mechanism. The goal of feature
extraction is to find a specific representation of the
data that can highlight relevant information [7]. This
representation can be found by maximizing a
criterion or can be a pre-defined representation.
Usually, a face image is represented by a high
dimensional vector containing pixel values (holistic
representation) or a set of vectors where each vector
summarizes the underlying content of a local region
by using a high level transformation (local
representation). In this section we made distinction in
the holistic and local feature extraction and
differentiate them qualitatively as opposed to
quantitatively. It is argued that a global feature
representation based on local feature analysis should
be preferred over a bag-of-feature approach. The
problems in current feature extraction techniques and
their reliance on a strict alignment is discussed.
Finally we introduce to use face-GLOH signatures
that are invariant with respect to scale, translation and
rotation and therefore do not require properly aligned
images. The resulting dimensionality of the vector is
also low as compared to other commonly used local
features such as Gabor, Local Binary Pattern
Histogram „LBP‟ etc. and therefore learning based
methods can also benefit from it [9].
III. WAVELET TRANSFORM
METHOD
Wavelet transforms have been one of the
important signal processing developments in the last
decade, especially for the applications such as time-
frequency analysis, data compression, segmentation
and vision [12]. During the past decade, several
efficient implementations of wavelet transforms have
been derived. The theory of wavelets has roots in
quantum mechanics and the theory of functions
though a unifying framework is a recent occurrence.
Wavelet analysis is performed using a prototype
function called a wavelet. Wavelets are functions](https://image.slidesharecdn.com/c601011823-160106081943/85/Efficient-Image-Compression-Technique-using-Clustering-and-Random-Permutation-2-320.jpg)

defined over a finite interval and having an average
value of zero. The basic idea of the wavelet transform
is to represent any arbitrary function f (t) as a
superposition of a set of such wavelets or basis
functions [11]. These basis functions or baby
wavelets are obtained from a single prototype
wavelet called the mother wavelet, by dilations or
contractions (scaling) and translations (shifts).
Efficient implementation of the wavelet transforms
has been derived based on the Fast Fourier transform
and short-length fast-running FIR algorithms in order
to reduce the computational complexity per
computed coefficient. All wavelet packet transforms
are calculated in a similar way. Therefore we shall
concentrate initially on the Haar wavelet packet
transform, which is the easiest to describe. The Haar
wavelet packet transform is usually referred to as the
Walsh transform [9].
DISCRETE WAVELET TRANSFORM
Image data input is shown at left in the diagram.
The DWT coefficient buffer at right in the diagram
stores wavelet coefficients computed by the DWT
stage. The program flow in the diagram produces
DWT coefficients for a single segment. Once the
coefficients corresponding to a segment have been
computed and placed in the buffer, the BPE stage can
begin encoding that segment. The BPE stage relies on
all of the coefficients in a segment being available
simultaneously [6]. The calculation of a DWT
coefficient depends on image pixels in a limited
neighborhood. Consequently, when images are
encoded using more than one segment, it is often
possible to implement the DWT stage so that DWT
coefficients for a segment are produced without
requiring input of a complete image frame. For
example, in a push-broom imaging application, DWT
coefficients may be produced in a pipeline fashion as
new image scan lines are produced by the imager.
WAVELET PACKET IMAGE CODING
One practical way of constructing wavelet bases
is to iterate a two channel perfect reconstruction filter
bank over the low pass branch. This results in a
dyadic division of the frequency axis that works well
for most signals we encounter in practice. However,
for signals with strong stationary high pass
components, it is often argued that wavelet basis will
not perform well, and improvements can be generally
found if we search over all possible binary trees for a
particular filter set, instead of using the fixed wavelet
tree [19]. Wavelet packet transforms are obviously
more general than the wavelet transform, they also
offer a rich library of bases from which the best one
can be chosen for a fixed signal with a fixed cost
function. The advantage of the wavelet packet
framework is thus its universality in adapting the
transform to a signal without training or assuming
any statistical property of the signal.
IV. PROPOSED METHOD
In this section describe the proposed algorithm
for image compression using wavelet transform and
particle of swarm optimization technique. Basically
in this algorithm POS are used for removal of
redundant structure of packet in common similar
block and create separate block and both block
supply to HCC matrix and finally image are
compressed. For the searching of redundant structure
block and non-redundant structure block used fitness
constrains function, those structure satisfied the given
constraints are called non redundant structure else
redundant structure. The proposed algorithm is a
combination of integer wavelet packet transform
function, particle of swarm optimization and HCC
matrix. Now the process of algorithm divided into
three sections. Section first discusses the generation
of packet, section two discusses the optimization of
packet and section three discusses the HCC code
matrix for compression. For the grouping of packet
used cluster algorithm. Cluster algorithm group the
similar packet and dissimilar packet.

The proposed algorithm is a combination of integer wavelet packet transform function, particle of swarm optimization and HCC matrix. Now the process of algorithm divided into three sections. Section first discusses the generation of packet, section two discusses the optimization of packet and section three discusses the HCC code matrix for compression. For the grouping of packet used cluster algorithm. Cluster algorithm group the similar packet and dissimilar packet. Figure 2: Proposed model of image compression.

VI. CONCLUSION AND FUTURE WORK In this paper we proosed a cluester based image compression technique.the cluester based image compression techniqe used k-means cluestering technique for the grouping of packet. In the particle of swarm optimization process define the fitness constraints according to the diffrence value of structure refrence packet. if diffrence of packet is zero value assigned 1 and the diffrence value get value assined 0. both similar and disimilry packet collect in two different unit and paases throgh HCC matrix after that image is compressed. the proposed algorithm implemenrt in matlab software with version 7.14.0. algorithm used hear wavelet faimly process for decompostion of image. the decomposed transfrom function passes through coding and generates packet transfrom. for the valiadtion of proposed algorithm used another image compression technique such as JPEG,PCRT and compostie algorithm. for the valuation of parameter used two standard parameter one is PNSR and another is compression ratio. our emprical valaution of PSNR and C.R shows that better value in comression of other compression algorithm. The proposed algorithm is very efficient in terms of PSNR value and C.R instead of PCRT algorithm and JPEG based compression technique.
