Neural network parametrized level sets for image segmentation
Otmar Scherzer, Cong Shi, Thi Lan Nhi Vu
Chan-Vese algorithms have proven to be a first-class method for image segmentation. Early implementations used level set methods with a pixelwise representation of the level set fu…

Neural operators for solving nonlinear inverse problems
Otmar Scherzer, Thi Lan Nhi Vu, Jikai Yan
We consider solving a probably infinite dimensional operator equation, where the operator is not modeled by physical laws but is specified indirectly via training pairs of the inpu…
