Abstract

Radial discrete orthogonal moments are often used in characterizing image shapes for applications in pattern recognition and image analysis for their good properties. In this paper, a new set of radial Krawtchouk moments is presented. Compared with classical radial discrete moments, the proposed moments take a new sampling method, which uses variational number of sampling point for different radius. In addition, a new discrete orthogonal vector set is constructed by making the discrete Krawtchouk polynomials orthogonal in radial direction to the discrete Krawtchouk polynomials orthogonal in circumferential direction. Experimental results show that the proposed moments have good performance in image reconstruction and computing efficiency.
