Abstract

Because of ubiquitous irregularities among texture patterns in real images, texture representation has long been a challenge for image analysis. Approaches such as wavelet transforms that use fixed-sized windows to extract local features are popular for texture identification and classification. However, due to the unawareness of texture scales and boundary locations, those block-based approaches have limited success for image segmentation. In this paper, we present a novel algorithm that tends to generate statistical descriptors that are adaptive to the variation of texture patterns based on a simple rule of pruning and concatenating the approximately repetitive patterns. In the context of image segmentation, the color information that is used by the popular mean shift segmentation algorithm is usually not sufficient for good segmentation performance. We alleviate this problem by first preprocessing the image with the proposed method to generate a "texture map" which then becomes the input image representation for the mean shift segmentation algorithm. The experimental results demonstrate the robustness and effectiveness of the proposed texture representation.
