Title
Multiscale colour texture retrieval using the geodesic distance between multivariate generalized Gaussian models.
Abstract
This contribution concerns the retrieval of colour tex- ture. The interband correlation structure is considered by modeling the heavy-tailed image wavelet histograms with a multivariate generalized Gaussian. As a similar- ity measure we propose to use the Rao geodesic distance, which, in contrast to the Kullback-Leibler divergence, ex- ists in a closed form for any fixed value of the shape pa- rameter of the distribution. We apply this in several re- trieval experiments. The modeling of the interband cor- relation significantly increases retrieval rates, while the geodesic distance is shown to outperform the Kullback- Leibler divergence. A multivariate Laplace distribution yields better results than a Gaussian, indicating the po- tential of a model with variable shape parameter together with the geodesic distance.
