Gradient-threshold edge detection based on the human visual system
Author(s): Fuzheng Yang; Yilin Chang; Shuai Wan

Paper Abstract

We present an improved method that is suitable for gradient-threshold edge detectors. The method takes into account the basic characteristics of the human visual system and masks the gradient image with the luminance and the activity of local image before edge labeling. An implementation of this method on a Canny detector is described as an example. The results show that the edge images obtained by our algorithm are more consistent with the perceptive edge images.
