Multigrid algorithm based on hybrid smoothers for variational and selective segmentation models

Automatic segmentation of an image to identify all meaningful parts is one of the most challenging as well as useful tasks in a number of application areas. This is widely studied. Selective segmentation, less studied, aims to use limited user-specified information to extract one or more interesting...
