Texture image classification and segmentation using RANK-order clustering

Abstract

Image analysis using texture as a spatial feature can be employed to segment regions of a complex scene or in the classification of surface materials. The relationship between most textural images and their description is mathematically intractable. In this paper the authors propose a new statistical measure, which is not based on a pre-defined formulation. Here, the local information in all directions around a pixel and its neighbourhood is represented in a 'directional RANK-strength' vector. The proposed method leads to texture classification and segmentation methods. Both algorithms have been tested on natural images with results in agreement with perceived ones.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
