【Abstract】 The cellular neural network (CNN) is a powerful tool for image processing and has been used for artificial vision,video compression,image fusion,motion and pattern recognition.This paper presents a set of new CNN templates for recovering convexity of disturbed convex objects in digitized gray scale images.The computer simulation showed that comparing to the recognizing operator,the CNN can recover more effectively degraded convex circles by Gaussian noise.It is expected that the new CNN templates can be used for analyzing electronic diffraction patterns (EDPs) of crystal and star images in the Galaxy.更多还原
