Modified JPEG Image Compression Algorithm for Lossy Image Compression

Abstract

In this paper, the focus is given on the Implementation of modified JPEG Image compression
algorithm. A lossy compression scheme is an approach to represent the same data
approximately in the image, so that less memory is being used to represent the image.
Humans can’t see colors at high frequency this benefit mainly utilized in JPEG compression
scheme. These high frequencies located points are actually the data points in the image that
are removed during the compression. Modified JPEG compression works best on images with
smooth color transitions and textured images. In this paper the Modified method and
traditional method JPEG compression scheme is compared on basic of PSNR and
Compression Ratio.
