Parametric Total Variation Models

Image Segmentation is often formulated as a minimization problem, where every possible labeling is assigned an energy. The idea is that the segmentation with the lowest energy corresponds to a good segmentation.

Recent research has shown that some of the minimization problems arising in image segmentation can be solved exactly. However, most energies used for segmentation depend on some external parameters in addition to the labeling. This work shows that there are some problems which can still be solved exactly. For these problems, both the optimal parameters and labeling are found.
