Abstract

In this paper is offered one new algorithm for global description of pre-segmented objects in a halftone image. The new algorithm has relatively low computational complexity than the famous Mellin-Fourier transform and permits multi-layer access which enhances the search by content in indexed image databases. The new algorithm is based on the previously developed methods of the inverse pyramid decomposition and of the truncated modified discrete Mellin-Fourier transform, which are combined here.
