Adaptive processing integrating the anisotropic diffusion for image edge and detail, and the nonlocal means filter for texture is present in image denoising. Meanwhile, image sharpening is emphasized even if in a single denoising task. The two strategies of feature-dependent adaptive processing and image sharpening give better results compared with some related methods in experiments.

Keywords:Computer image processing; image denoising; image decomposition; anisotropic diffusion; nonlocal filter; adaptive method
