Image Denoising via Sparse Representation Over Grouped Dictionaries With Adaptive Atom Size

Image Denoising via Sparse Representation Over Grouped Dictionaries With Adaptive Atom Size

The classic K-SVD based sparse representation denoising algorithm trains the dictionary only with one fixed atom size for the whole image, which is limited in accurately describing the image. To overcome this shortcoming, this paper presents an effective image denoising algorithm with the improved d...
