Image Restoration using Plug-and-Play CNN MAP Denoisers
Siavash Arjomand Bigdeli, David Honzátko
Plug-and-play denoisers can be used to perform generic image restoration tasks independent of the degradation type. These methods build on the fact that the Maximum a Posteriori (MAP) optimization can be solved using smaller sub-problems, including a MAP d ...
SCITEPRESS2020A Computational Framework For Two-Dimensional Random Walks With Restarts
The treatment of two-dimensional random walks in the quarter plane leads to Markov processes which involve semi-infinite matrices having Toeplitz or block Toeplitz structure plus a low-rank correction. We propose an extension of the framework introduced in ...
