Abstract (in Japanese) (See Japanese page) 
(in English) A sparse coding is one of the generative model for images, and can obtain bases that indicates features of an image under sparsity condition. In order to perform the decomposition, it is necessary to estimate the number of the bases that are correspond to the micro structures of the image textuers. However, it is difficult to estimate the number of the different micro structures from an unknown image. In this paper, we propose an iterative method to estimate the number of the micro structures of the images through the shift-invariant sparse coding. In experiments, the proposed method is applied to the texture image separation. By this experiment, we demonstrated that the proposed method is effective for the representation of the texture images.
