Abstract
Accroding to the limitation of the traditional methods in detection quality and noise resisting ability,this paper presents a novel method based on image feature to detect edge. This method considers the effect of gradient feature,phase feature and noise at the same time. It makes oriented energy and brightness gradient got by histogram different operator as image feature to detect edge. The computed feature values are trained and the feature mean values are got、 With the rule of distance closest, the pixels are classified and thereby the edge of the image is found. A function is established to evaluate the quality of edge. It is proved that the method can get good detection results and avoid the interference of noise to some extent.关键词
