Abstract:

A noise removal technique using partial differential equations (PDEs) is proposed. It combines a second-order filter with a fourth-order filter. The combined method takes the advantage of both filters since it can preserve edges and at the same time avoid the blocky effects in smooth regions. The experimental results illustrate the effectiveness of the model in image restoration.
