Abstract :
Studies the parallel algorithms in image processing based on the YH supercomputer, and pay attention to the parallel algorithms of image enhancement and edge detection. These algorithms are programmed in VECTAN. The experiment results show the general speed up ratio of edge detection is 2~8, the speed up ratio of image enhancement is about 20. It greatly increases the speed of image processing
