Abstract

This paper presents a structure adaptive anisotropic filtering method and its applications. It differs from other techniques in that instead of using local gradient as a means of controlling the anisotropism of the filters, it uses the local intensity orientation of level contours and its curvature to control the shape and the extent of the filter kernel. This ensures that edges and corners are well preserved throughout the filtering process.
