It is known that many image enhancement methods have a tradeoff between noise suppression and edge enhancement. In this paper, we propose a new technique for image enhancement filtering and explain it in human visual perception theory. It combines kernel regression and local homogeneity and evaluates the restoration performance of smoothing method. First,(More)
Image filtering is an important problem in image processing. Many algorithms such as adaptive filter, total variation method in this field are efficient and practical. In this paper, the local homogeneity method is employed which result in the homogeneity image (H-image). The high and low values of the H-image correspond to possible region boundaries and(More)
