In this talk, we will explore the relationship between graph cut, convex
relaxation and some recent continuous max-flow approaches proposed in the
literature. Especially, we will see the continuous versus discrete
relationship between them. There are two advantages with these approaches:
1) different fast numerical algorithms have been used for these approaches;
2) global minimization can be guaranteed for some nonconvex problems. We
shall describe the connections between some of these algorithms.
Image restoration and segmentation will be used as examples for applications
of these algorithms. Extended application of ROF model, global minimization
of the Chan-Vese model and different global minimization approach for
multiphase labeling problems will be presented. This talk is based on
collaborative work with Bae, Yuan, Liu and other collaborators.
