Research and realization of recognition for shoe soles based on outline feature
基于轮廓特征的平面鞋印自动识别算法的研究和实现*

This paper proposed a method of recognition for shoe soles based on outline feature,which found that the two outline points at the longest distance according to the feature that the length of shoe sole was longer than any other parts in a shoe sole,and then calculated the angle shaped by the two points and horizontal axes.It proofreaded the shoe soles in terms of angle calculated,extracted 9 features of shoe sole automatically,and measured the similarities of shoe soles by Euclidean distance.The experimental results show the method used to recognize shoe soles is effective.
