Chengzhuan Yang, Lincong Fang, Benjie Fei, Qian Yu, Hui Wei

Abstract: Highlights•We propose a novel multi-level contour combination feature method.•Our method solves the intra-class variation and complex deformation of a shape.•We are the first to study the shape from the multi-level perspective of contours.•The performance of our method exceeds the prior state-of-the-art approaches.
