Ningning Zhou, Zhengxu Zhao, Long Hong, Yulong Deng · 2008
Image edge is a basic feature of images, and edge detection is a preprocessing technique in the field of image processing. This paper presents a novel image edge detection algorithm derived from the similarity degree of edge pixels based on the measuring of medium truth scale. For further edge refining, two thresholds and restraint on non-minimum value in domain are applied to the algorithm. Simulation results show that the algorithm can effectively eliminate noise , successfully preserve the image edge details, produce better edge detection result and is more effective and have wider applications compared with that of the classic algorithms.
