Regularized Shock Filters and Complex Diffusion
Shock filters deblurring denoising image enhancement complex diffusion image features
2010/1/7
We address the issue of regularizing Osher and Rudin’s shock filter, used for image deblurring, in order to allow processes that are more robust against noise. Previous solutions to the problem sugges...
