Liyan Chen, Longzhao Zhong, Beizhan Wang · 2016
The paper proposes a dynamic shape context retrieval algorithm based on statistic. It selects shape's feature point's number dynamically, and statistics the number of target shape's feature points in different area block to form a contour feature point histogram. Finally, measuring the similarity is used dynamic programming algorithm. This method can selects the number of feature points adaptively, and it can reduces the effect of deformation on the structural feature description. Experimental results show that the proposed algorithm is effective.
