Abstract :
A new set of radial orthogonal moment functions were presented based on the discrete Fourier functions and the discrete Chebyshev polynomials, which can be effectively used in the image analysis. The proposed moments take a new sampling method that overcomes the default of classical method. In addition, a new discrete orthogonal system is constructed. The experimental results show that the new radial moments are superior to the conventional moments in image reconstruction and computing efficiency.
