%X A novel shape representation and registration method based on Hough spectrum is developed in this paper. The weighted-average Hough spectrum(WAHS) is defined for the representation of arbitrary shapes, and the translation, rotation, scale and periodic properties of WAHS are summarized and proved. When registration, the parameters of rotation and scale can be estimated easily from the phase and amplitude of WAHS, and the parameter of translation can be estimated in the Hough density space. Experiments show that the method is effective to estimate the parameters of translation, rotation and scale, and is immune to noise and overlapping.
