报告摘要：We propose an exact convex formulation of the Chan-Vese model with 4 regions. A global solution is guaranteed if the data term satisfies a (mild) submodularity condition. Theoretical and experimental arguments are given that such a condition will hold in practice for the most commonly used type of data terms. Otherwise, a convex truncation scheme is proposed which can produce global solutions in practice, should this not be the case.
