Abstract

Aiming at the problem of low recognition accuracy of traditional target recognition algorithms for occluded targets, this paper proposed an occluded target recognition algorithm based on contour segmented feature description. The algorithm firstly used the discrete curve evolution algorithm to preliminarily divide the target contour, and optimized the segment according to the undulation degree of the segment, and obtained effective segments that completely described the characteristics of the target contour. Then, the algorithm analyzed the similarity of the height function features between the contour segments through the dynamic programming algorithm, and used feature saliency to evaluate the importance of segment features relative to the overall feature of the target. Further, the algorithm combined the similarity between the segments with their feature saliency to obtain the joint similarity that measured the recognition accuracy. Experiments on the MPEG-7 test set prove that the algorithm can effectively match and recognize occluded targets, and the recognition rate is better than common occluded target recognition algorithms.
