Digital filtering of images in a residue number system using finite-field wavelets

Abstract

A new approach for processing images based on joint application of the residue number system and finite-field wavelets is proposed in this work. It is shown that the residue number system with simple modules can be used for implementation of the digital processing of signals using finite-field wavelets. The principle of organization of computations in the wavelet transform of images in the residue number system is proposed. There are given examples showing how this method can be used for compression of images and protection of confidential information.
