Fast Radial Harmonic Moments for Invariant Image Representation

摘要

The main objective of this paper is to reduce the reconstruction error and fast calculation of Radial Harmonic Fourier Moments (RHFM). In the proposed work, the fast RHFM has been applied on the original gray image for reconstruction. Before applying RHFM on grayscale image, the image in portioned into radial and angular sectors. Results are compared with traditional methods. The proposed approach results in better reconstruction error. Also, moments can be calculated at high speed using proposed approach.
