Abstract
A new unsupervised algorithm for texture segmentation is proposed in this paper. The new scheme is based on the idea that texture features changes abruptly near boundaries. The image is first looked as regions of 5 x 5 masks and an edge detection algorithm based on all four directions with respect to central pixel is applied and primitive morphological concepts are proposed to change the central pixel. The validity of the proposed method is also considered by experimental results.
