Image Analysis by Fourier-Chebyshev Moments
Yu Jing · Journal of Optoelectronics·laser · 2005
A new set of orthogonal moment functions were introduced based on the discrete Fourier functions and the discrete Chebyshev polynomials.The Fourier-Chebyshev moments can be effectively used as image features in the analysis of two-dimensional images.The paper constructs the moments in the discrete orthogonal domain of the image coordinate space.The property makes the images be reconstructed by no more than N×N moments.The experimental results indicate that the Fourier-Chebyshev moments are superior to the conventional moments such as Legendre moments and Zernike moments in the analysis of complex images.
