Most methods based on level set do not have the stop criterion based on the global minimum
instead they employ the iteration number as stop criterion. This paper proposes an improved Chan-Vese model
by adding a constrained term
making the functional converge to global minimum
and presents the stop criterion based on global minimum
without setting iteration number in advance. Experimental results show that the proposed model can segment images correctly under the new stop criterion. Compared with the Chan-Vese model
it has a faster convergence
3~6 times faster than Chan-Vese model
and is of good general use.
