Abstract (in Japanese) (See Japanese page) 
(in English) Recently we have presented moving-image denoising with 3-D Mean-Separation-type Short-Time DFT and demonstrated that it achieves a performance comparably to the state-of-the-art denoising methods. Firstly this paper deals with sparsity of 3-D DFT coefficients of a moving image both theoretically and experimentally. Secondly for the statistical modeling of 3-D DFT coefficients of a moving image this paper takes up a 2-component spherically-symmetric Gaussian mixture probability model based on a degradation model and signal’s sparsity, and gives a summary of theoretical results on its basic properties and its model-parameter estimation. Thirdly this paper discusses the issue of how to apply it to moving-image restoration.
