In order to solve the GVF Snake algorithm for the problem of slow, this paper first consider the GVF algorithm rake's time, then divide the algorithm into five steps. Follow by the five time part for analysis and get the improvement method to solve the problem that the GVF Snake algorithm spend too much time, then get the method to improve the speed by reducing the force field calculation of the area and improve the external force field to accelerate the computation speed. Finally, experiment authentications improve the algorithm speed improved significantly.
