In order to solve the problems of steel surface defects detection and feature extraction under complex image background, shorten the design cycle for vision system, and increase its utility, a parallel computation platform and a video simulation platform were designed. Based on that, a hybrid method integrated with parallel computing, video simulation, and evolutionary computing, was proposed to solve the problem of steel surface defects detection and feature extraction. New ideas were stimulated for intelligent visual information processing. Experiments show that, the method not only is viable, but also can improve the accuracy and immediacy during defects detections.
