Image compression is an art used to reduce the size of a particular image. The goal of image compression is to eliminate the redundancy in a file’s code in order to reduce its size. It is useful in reducing the image storage space and in reducing the time needed to transmit the image. Image compression is more significant for reducing data redundancy for save more memory and transmission bandwidth. An efficient compression technique has been proposed which combines DCT and Huffman coding technique. This technique proposed due to its Lossless property, means using this the probability of loss the information is lowest. Result shows that high compression rates are achieved and visually negligible difference between compressed images and original images.

Keywords: Huffman coding, Huffman decoding, JPEG, TIFF, DCT, PSNR, MSE
