摘要
针对GVF Snake算法速度慢的问题,从GVF Snake算法运算的时间入手,将算法分为五个步骤,而后对这五个步骤花费的时间进行分析,得出改进GVF Snake算法速度的方法,通过减少力场计算面积和改进外力场来加快运算速度,最后通过实验验证,改进算法速度明显提升。
In order to solve the GVF Snake algorithm for the problem of slow, this paper first consider the GVF algorithm take＇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.
