Hyperparameter selection for the Discrete Mumford-Shah functional
Hyperparameter selection for the Discrete Mumford-Shah functional
This work focuses on joint piecewise smooth image reconstruction and contour detection, formulated as the minimization of a discrete Mumford-Shah functional, performed via a theoretically grounded alternating minimization scheme. The bottleneck of such variational approaches lies in the need to finetune their hyperparameters, while not having access to ground truth …
