| Abstract: | This paper describes a method to detect noise-blurred image's edge by feedforward neural network with modified BP algorithm. Owing to neural network's parallel characteristic, non-continuous contour may be marked by low-thresholded image and high-thresholded image, both of which were obtained from Canny' s optimal edge operator, more quickly and precisely. |
