A REVIEW PAPER ON COLOR IMAGE COMPRESSION TECHNIQUES

Abstract

In this paper we will study the concept of color image compression and the different techniques applied on the
color Image Compression. ColorImage Compression is the technique of reducing the image size without degrading the
quality of the image and also reducethe storage requirement area. Color Image Compression is the solution associated with
transmission and storage of large amount of information for digital Image.Image Compression has become is an
indispensable part of digitized image storage and transmission. Compression of an image is necessary before storing and
transmitting it due to its limitation of storage and bandwidth capacity.Image compression makes the faster transmission
process as well as provides larger bandwidth and also provides security for the data transmission. In this paper,two
techniques of color image compression using DCT(Discrete Cosine Transform) and DWT(Discrete Wavelet
transform).Image compression system between DCT and DWT using JPEG (Joint Photographic Experts Group) and PNG
(Portable Network Graphics) color images.
