Abstract

With constant development of multimedia technology, large amount of image information is given more and more attention by people. High-quality image compression becomes the hot subject of current study. In this paper, basic on the algorithm of JPEG image compression code and applying the periodicity and symmetry of cosine function, we have made proper improvement to the method of discrete cosine transform reducing large amount of cosine and multiplication operations in computer and greatly improving the compression rate. At last, Matlab software was adopted to emulate and validate standard images. Results of experiments show that compression rate of images has been improved within a large compression scope.
