A new shape descriptor is presented in this paper, which is based on the centroid-radii model model and the Haar wavelet transform. With this descriptor, we can achieve more accurate shape feature and implement more efficient retrieval under multi-resolution. In addition, our method is robust to translation, scaling and rotation. The experimental results show the competitiveness of this descriptor.
