Texture classification based on the generalized gamma distribution and the dual tree complex wavelet transform
Abstract
This paper deals with stochastic texture modeling for classification issue. A generic stochastic model based on three-parameter Generalized Gamma (GG) distribution func-tion is proposed. The GG modeling offers more flexibility pa-rameterization than other kinds of heavy-tailed density devoted to wavelet empirical histograms characterization. Moreover, Kullback-leibler divergence is chosen as similarity measure between textures. Experiments carried out on Vistex texture database show that the proposed approach achieves good classification rates.
