Abstract: Conventional edge detection algorithms suffer from the shortcomings of undetected and so on. This paper proposes an algorithm based on UGM model for improving considerably the performance of image edge detection. This paper just adds some pertinent remark to listing the two topics of explanation: how to realize image edge detection based on UGM model; the results of analysis. In the first topic, this paper adds an enhancement parameter [q] in the error image to improve the edge definition. This paper does experiments and analyzes their results. The analysis of the experimental results show preliminarily that the UGM model can not only effectively detect the information of image edges but also keep their details.
