约束项 meaning in Chinese

bound term

This method connects the discrete points processed in the level set method to form a smooth curve , thus transforms the discrete problem to continuous one . constraint entry is added to the curve according to the actual demand , and satisfactory result is obtained in experiments . the results show that the algorithm is effective in the actual applications
基于链码的水平集方法把原先水平集方法中处理的离散点,利用链码易于表示曲线的特点,连接成一条光滑的曲线,这样就把离散问题转化为连续问题,利用曲线的连续性和光滑性,根据实际问题的需要,对曲线加入外部约束项控制,在实验中获得了满意的结果,在实际应用中达到了预期的效果。
