Using Residue Number System for Edge Detection in Digital Images processing

In this paper, we propose a scheme for Edge Detection in Digital Image based on the Residue Numbers System which leads to performance of the integration circuits with high speeds and high security and low power for Digital Image Processing. In this method, Edge Detection in Digital Images performs based on convolution operation between pixel values and applicable mask and also saving of obtained values of edges in the LUT memories and threshold operations by using values in Look-Up table. All operations in this method perform in Residue Numbers System. Then we design circuits for edge detection and of decimal to residue conversion and vice versa which in is used Matlab software and also VLSl tools for simulation. Preliminary simulation results show that the proposed scheme has the ability of edge detection of digital images.
