Summary:Image processing technology has been large-used in industrial production. All kinds of image data have external or internal interference inevitably. Preprocess is necessary for image to protect image process quality. Preprocess adopts Gray processing, image enhancement, image gray, median value filter, gray stretch etc, these modify the unsatisfactory image. The results show well effect. Especially it can locate accurately more noise, lower contract so as not to locate or divide well after preprocessing.
