Abstract

Many color image enhancing techniques have been proposed to eliminate noise and uninteresting details from an image, without blurring semantically important structures such as edges. PDE - based methods have been proposed to tackle the problem of image deno ising with a good p reservation of edges and also to explicitly account for intrinsic geometry. The existing method can be viewed as generalization of the Bettahar – Stambouli filter to multivalued images. The proposed algorithm is based on using single vec tors of gradient magni tude and the fourth order derivatives as a manner to relate different color components of the image. The Partial Differential Equation based algorithm is more efficient than existing models and some previous works at color images denoising and sharpens the edges efficiently withou t creating false colors.
