Total variation for cyclic structures: Convex relaxation and efficient minimization

Abstract

We introduce a novel type of total variation regularizer, TVS1, for cyclic structures such as angles or hue values. The method handles the periodicity of values in a simple and consistent way and is invariant to value shifts. The regularizer is integrated in a recent functional lifting framework which allows for arbitrary nonconvex data terms. Results are… (More)
