Abstract :
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 region interiors respectively. Finally, an adaptive filter method is proposed which combines the image homogeneity and local discontinuities. Comparative experiments indicate that our algorithm yields favorable smoothing results.
