摘要：The research object of this paper is the self_crosses of contour in parameter active contour model with shrink strategy (PACMS). For studying the object, parameter active contour model is improved to rapidly converge and reduce number of the self_crosses of contour. The concept of self_cross in PACMS is introduced and the influence of it on the evolution of PACMS is presented. With the improved model, the existence of self_cross in PACMS is shown. The treatments of self_cross on contours in the current literatures are analyzed. A model of describing the self_crosses is set up and an improved method of detecting and treating the self_crosses in PACMS is put forward. The experiment results of the new method are given and the comparison among the new method and other methods of detecting and treating the self_crosses are made. The result shows that the new method is more efficient than the other method of detecting self_crosses on contours.
