The empirical research shows that the C-Vmodel with negative area parameter can segment some images that the original C-Vmodel is not applicable to.

Compared with traditional image segmentation methods, C-Vmodel has some special advantages: it can accommodate itself to the changes of the object's Geometric topology and obtain continuous boundary.
