Abstract
In this talk, I will discuss inverse problems' discretization using box splines. I use linear box splines on a Cartesian grid. For them, I derive that both total variation and Hessian total variation can be computed using convolutions with some simple filters. This exact discretation is then used for faster implementation of standard inverse problems.
