Texture retrieval using mixtures of generalized Gaussian distribution and Cauchy–Schwarz divergence in wavelet domain
作者:
Highlights:
• We propose Cauchy Schwarz divergence CSD for texture retrieval.
• Wavelet coefficients are modeled by mixture of generalized Gaussians MoGG.
• We derive a closed-form of CSD between MoGG for fixed parameter shape.
• We use the Monte-Carlo approximation for CSD in the general case.
• We evaluate the performance in terms of the average retrieval rates and the computational time.
