Image Denoising by Sparse 3-D Transform-Domain Collaborative Filtering
Articolo
Articolo
Kostadin Dabov; Alessandro Foi; Vladimir Katkovnik; Karen Egiazarian · IEEE Transactions on Image Processing · 2007
We propose a novel image denoising strategy based on an enhanced sparse representation in transform domain. The enhancement of the sparsity is achieved by grouping similar 2-D image fragments (e.g., blocks) into 3-D data...
