A Generative Model of Textures Using Hierarchical Probabilistic Principal Component Analysis

Abstract (in Japanese) (See Japanese page) 
(in English) Modeling of natural textures in an important task for microscopic structure of natural images. Portilla and Simon-
celli proposed a generative texture model, which is based on the mechanism of human visual systems, with a set of texture
features. On the other hand, the texture features, used in Portilla’s model, have redundancy between its components, came from typical natural textures. We propose a contracted texture model which provides a dimensionality reduction for the Portilla’s feature. This model is based on a hierarchical principal components analysis using group structure of the feature. In the experiment, we reveal a fewer effective dimensions for a texture dataset with proposed method. And we also demonstrate how well the textures can be synthesized from the reduced texture representations.
