Abstract:

This article discusses an improved model  of the Snake model,which is based on the vector field convolution model.This model serves as the general form for the GVF model.The convolution model is applicable to a wider range and has better robustness than the traditional model.By comparing the classic and traditional Snakes models and analyzing the contours,noise sensitivity and complexity of the algorithm,it is shown that VFC does not have a high requirement on noise and initial contour sensitivity and that its design remains to be improved.
