Texture features based on texture spectrum
Texture is an important spatial feature useful for identifying objects or regions of interest in an image. This paper presents a new set of textural measures derived from the texture spectrum. The proposed features extract textural information of an image with a more complete respect of texture characteristics (in all the eight directions instead of only one displacement vector used in the co-occurrence matrix approach). Some of Brodatz's natural texture images have been used for evaluating the performance of the features in the characterization and discrimination of the texture aspects of images. Some of the traditional texture features, extracted from the co-occurrence matrix, have also been used for comparison with the new measures in the discrimination of different lithological units of an airborne synthetic aperture radar image. Promising results are obtained and presented in this paper.
