To address the problem, we define a novel similarity function including two parts in this paper. The first part is Hausdorff distance between shapes which is calculated by exploiting shape context that is rotation and scale invariant as the distance metric. The second part is the cost of matching between centroids. Unlike the traditional method, we use the centroid as reference point to obtain its shape context that embodies global information of the shape. Experiment results demonstrate that the function value between shapes is rotation and scale invariant and the matching accuracy of our algorithm is higher than that of previously proposed algorithm on the MEPG-7 database.   Multifractal structure of the product measure of two independent general subordinators' occupation measures 期刊论文  iSwitch采集 Science in china series a-mathematics, 2009, 卷号: 52, 期号: 8, 页码: 1785-1795 作者:  Kong LingTao;  Hu XiaoYu 收藏  |  浏览/下载：17/0  |  提交时间：2019/05/10 General subordinator  Occupation measure  Hausdorff measure  Multifractal spetrum   Hausdorff dimension of generalized statistically self-affine fractals 期刊论文  OAI收割 ACTA MATHEMATICA SCIENTIA, 2004, 卷号: 24, 期号: 3, 页码: 421-433 作者:  Yu, JG;  Ding, LX 收藏  |  浏览/下载：21/0  |  提交时间：2015/07/15 self-affine contraction map  statistically recursive set  statistically self-affine set  Hausdorff measure  Hausdorff dimension  singular value function   The multifractal Hausdorff and packing measure of general Sierpinski carpets 期刊论文  OAI收割 ACTA MATHEMATICA SCIENTIA, 2000, 卷号: 20, 期号: 3, 页码: 313-321 作者:  Huang, LH;  Yu, JH 收藏  |  浏览/下载：17/0  |  提交时间：2015/12/01 multifractal Hausdorff measure  multifractal packing measure  general Sierpinski carpets
