Abstract :
In this paper, a local scale measure is presented for the detection of homogeneous regions in an image. Then, based on region homogeneity, an adaptive nonlocal means filter (ANLMF) is proposed. In this method, the neighborhood window size for denoising varies adaptively, according to the local scale measure. Experiments show that the proposed filter (ANLMF) is better than the state-of-the-art nonlocal means filter (NLMF).
