A massively parallel multi-level approach to a domain decomposition method for the optical flow estimation with varying illumination
Diane Gilliocq-Hirtz, Zakaria Belhachmi
We consider a variational method to solve the optical flow problem with varying illumination. We apply an adaptive control of the regularization parameter which allows us to preser…

A Direct Method for Photoacoustic Tomography with Inhomogeneous Sound Speed
Zakaria Belhachmi, Thomas Glatz, Otmar Scherzer
The standard approach for photoacoustic imaging with variable speed of sound is time reversal, which consists in solving a well-posed final-boundary value problem for the wave equa…
