Digital Straight Segment Filter for Geometric Description

In this paper, an algorithmic scheme is proposed to estimate different local characteristics of image structures using discrete geometry tools. The arithmetic properties Digital Straight Lines and their link with the Farey sequences allow introduction a new directional filter. incremental process, it provides geometric information at each point in image, such as length, orientation thickness longest Segment passing through that point. Experiments on binary grayscale images are show interest tool. Comparisons well-known morphological filter for also presented.
