Abstract:

In this talk, I will review some total variation based image processing models, including deblurring, inpainting, zooming, partial Fourier reconstruction and impulsive noise removal. We emphasize that all these problems preserve favorable structures so that efficient ADMM algorithms can be designed. In particular, the matrix structure of blurring matrix will be discussed under different boundary conditions, which plays key role in efficient implementation of the algorithms.
