一种利用轮廓朝向特征进行形状匹配的方法
An Object Shape-matching Method Using Contour Orientation Feature
摘要
Abstract
At present,the biggest challenge is how to deal with changes of object scale effectively in most of the shape-based object rec-ognition model.In this paper,we put forward an algorithm of detecting orientations in digital images,which can extract satisfactory orien-tation maps from complex images.Compared with the edge/line maps obtained by traditional algorithms,the orientation maps highlight salient semantic features,while suppressing trivial distractions.Moreover,they are closer to the real contour maps of objects.With the pro-posed model of orientation computation,we design an object recognition model based on shape matching,which combines the"orienta-tion feature"and"shape feature".The shape feature utilizes the angle information between the line segments to ensure the stability of the object scale.The orientation feature is obtained through the receptive field of simple cells and complex cells in visual pathway,which are integrated with adaptive contextual information for the shape matching of objects with complex background information.The experiments show that the model proposed can improve the efficiency of recognition on the basis of ETZH image library.关键词
