A Geometric Flow Approach for Region-based Image Segmentation
A Geometric Flow Approach Region-based Image Segmentation
2012/8/10
Geometric flows have been successfully used for surface
modeling and designing, largely because they are inher-
ently good at controlling geometric shape evolution. Vari-
ational image segmentation...
