Abstract :
A texture classification scheme is presented that is based on classifying spectral features derived from the two-dimensional Wigner-Ville distribution (WVD) using an iterative and unsupervised k-means classification technique. The proposed method is illustrated with the aid of both simulations and examples on physical microscopic images. The obtained results show that the WVD allows pertinent features of image regions to be extracted, and that the use of only these spectral features yields a satisfactory texture classification results
