Abstract
The need for a compression system to significantly reduce the size of high resolution gray-scale and full-color image (picture) files, which can range from 100 Kbytes to over 3 Mbytes, stimulated an extensive research program that resulted in the development of new image compression systems. These new compression systems, based on well established and suitable compression schemes which run on Graphic Signal Processor (GSP), can reduce image file sizes by a factor of more that 8:1 with only minor detectable image degradation. Image compression of such kind is of interest because GSP is now an integral part of display control. The need for separate and expensive DSP for Discrete Cosine Transform computation is eliminated. This paper will discuss the importance of this compression scheme in the GSP world in terms of cost, speed and performance.
