AB  - This paper addresses statistical-based texture modeling using wavelets. We 
      propose a new approach to represent the marginal distribution of the wavelet 
      coefficients using finite mixtures of generalized Gaussian (MoGG) distributions. 
      The MoGG captures a wide range of histogram shapes, which provides better 
      description and discrimination of texture than using single probability density 
      functions (pdf's), as proposed by recent state-of-the-art approaches. Moreover, 
      we propose a model similarity measure based on Kullback-Leibler divergence (KLD) 
      approximation using Monte Carlo sampling methods. Through experiments on two 
      popular texture data sets, we show that our approach yields significant 
      performance improvements for texture discrimination and retrieval, as compared 
      with recent methods of statistical-based wavelet modeling.
