General nonconvex total variation and low-rank regularizations: Model, algorithm and applications

作者:

Highlights:

• We propose a new algorithm for the general nonconvex TV+LR model and prove the convergence.

• The algorithm enjoys the advantage of just minimizing convex subproblems in each iteration. No inner loops are needed andthen it is easy to program the algorithm.

• A warm-up technique is used to accelerate the algorithm.
