Paper Abstract

This paper addresses the construction of the edge-preservation coefficient for anisotropic diffusion for image enhancement. We evaluate the performance of existing diffusion techniques in the presence of several corruptive processes. The results from this study were used to design a hybrid algorithm which capitalizes on the strengths of the current diffusion coefficients. The new edge-preserving algorithm adaptively determines the presence of noise or edges at each image location and selects the appropriate diffusion coefficient. The results generated from this algorithm exhibit improvements in mean squared error, signal-to-noise ratio, and visual quality. A comparative study shows the performance of the standard diffusion techniques and the hybrid algorithm for images corrupted by Laplacian-distributed, Gaussian- distributed, and 'salt and pepper' impulse noise.
