PMBP: PatchMatch Belief Propagation for Correspondence Field Estimation
Published on Oct 09, 20124705 Views
PatchMatch is a simple, yet very powerful and successful method for optimizing continuous labelling problems. The algorithm has two main ingredients: the update of the solution space by sampling and
