Abstract The geometric centre is taken as the origin in the traditional centroid-radii based shape description method, which makes it sensitive to noise, and slight changes in the boundary cause errors in matching. A robust method for 2-D shape description and matching is presented to solve this problem. It uses a polar transformation of the contour points to get the shape descriptor, and the maximum of the generalized Hough transform (GHT) mapping array is taken as the reference point. The experimental results on 3 benchmark test sets show that the proposed approach is invariant to translation, rotation and scaling. Furthermore, it achieves high performance in the retrieval of partially occluded and defect images.
