基于偏微分方程的对GAC模型的改进算法的程序实现，可以对图形进行分割，此程序中如改变迭代的次数，分割效果回会逐渐的变好，但速度会变慢，当迭代次数超过4000次以上，效果就不是很明显了-GAC model based on partial differential equations of the improved algorithm program implementation can be divided on the graphics, this program, such as changes in the number of iterations, segmentation results will be gradually changed for the better back, but the speed will slow down, when the number of iterations over 4000 or more times, the effect is not very evident
