Gaussian FoE model with correlations among color components

Abstract (in Japanese) (See Japanese page) 
(in English) Color images consist of some color components such as RGB, YCbCr. They have been often treated independently in usual image filters.
However, it would be natural to consider correlations among color components in color images.
In this paper we design a new prior probability for color images, which can take correlations among color components into account, by extending a fields of experts model with a Gaussian distribution, called Gaussian fields of experts (GFoE), and by using machine learning techniques.
We show that our proposed model gives better results than a GFoE which does not take correlations among color components into account with the same order of computational cost.
