Paper Abstract

Image denoising with second order partial differential equations (PDEs) often leads to undesirable staircase effect, namely, the transformation of smooth regions into piecewise constant regions. In this paper, staircase effect is analyzed in spatial frequency domain which is different from previous studies. A method of nonlinear diffusion based on Laplacian Pyramid is proposed. The experimental results show that the proposed method alleviates the staircase effect and leads to more natural restored images.
