The Blake-Zisserman model for digital surface models segmentation [PDF]
The Blake-Zisserman functional is a second-order variational model for data segmentation. The model is build up of several terms, the nature and the interaction of them allow to obtain a smooth approximation of the data that preserves the constant ...
