Deterministic and randomized Kaczmarz methods for with applications to color image restoration
Wenli Wang, Duo Liu, Gangrong Qu +1
We study Kaczmarz type methods to solve consistent linear matrix equations. We first present a block Kaczmarz (BK) method that employs a deterministic cyclic row selection strategy…

The photography transforms and their analytic inversion formulas
Duo Liu, Gangrong Qu, Shan Gao
The light field reconstruction from the focal stack can be mathematically formulated as an ill-posed integral equation inversion problem. Although the previous research about this…

Greedy randomized block Kaczmarz method for matrix equation AXB=C and its applications in color image restoration
Wenli Wang, Duo Liu, Gangrong Qu
In view of the advantages of simplicity and effectiveness of the Kaczmarz method, which was originally employed to solve the large-scale system of linear equations , we study…
