Abstract (in Japanese) (See Japanese page) 
(in English) This work proposes a denoising technoque with a two-dimensional (2-D) non-separable GenLOT for image denoising. In image denoising one of the most popular and well known techniques is the soft shrinkage proposed
by Donoho and Johnstone. However, the shrinkage function is not exible
since it depends on the universal threshold and the non-linearity makes the optimization complex. In order to mitigate these problems, an
orthonormal wavelet thresholding algorithm based on SURE-LET is proposed by Luisier. However, the method still has a disadvantage in representing diagonal geometric structures such as diagonal edges and textures dure to the separablity of an adopted transform. In order to solve the problem this work contributes to apply the 2-D non-separable GenLOT with the trend vanishing moments(TVMs). From some experimental results, it is that our method have a good perform with texture image.
