Abstract.
A novel technique for extracting texture edges is introduced. It is based on the combination of two ideas: the patch-based approach, and non-parametric tests of distributions. Our method can reliably detect texture edges using only local informa- tion. Therefore, it can be computed as a preprocessing step prior to seg- mentation, and can be very easily combined with parametric deformable models. These models furnish our system with smooth boundaries and globally salient structures.
