Abstract

Bilateral filter denoises image with edge preservation. It possesses two filters, one for homogeneous intensity region and other for sharp intensity changes. This paper proposes improvement in Bilateral filter by preserving texture and sharp changes in the image using range, standard deviation, entropy and gradient. For proper establishment, mathematical insight is given that explains why the proposed filter performs better than Bilateral filter in vicinity of texture and edges. Some important results are given to study the proposed algorithm.
