New method of contour initialization in GVF Snake model
GVF Snake模型中一种新的初始轮廓设置方法

A new method of contour initializaiton was proposed by analyzing the shortcomings of the huge waste of time and the failure of extracting some true contours in Gradient Vector Flow(GVF) Snake model.The multiscale edge detection based on wavelet transform could exactly distinguish all kinds of contours.The new contour initialization method based on wavelet transform could approach to the target boundaries.The experiment results show that this method reserves all the advantages of GVF Snake model and leads to the small searching range,decreased amount of GVF iteration and improvement of convergence speed.
