后一帧 meaning in Chinese

next frame

It is used to make sure that with a rifle for example , the bullet leaves when you can see the rifle firing , and not before or after ( or that would just be wrong )
它用来确定例如使用步枪的时候，当你可以看到步枪开火时子弹离开的那一帧的帧序号，不是前一帧也不是后一帧（总之就是那一帧）。
A good overall match is obtained in a few iterations . because the difference between moving object in successive frames is unobvious in color video sequences , the last position of locating in the former frame just turns into the initial position of the latter frame which solves the problem of determination of initial position
由于在彩色视频序列中,相继两帧之间运动物体的差异很小,因此将主动形状模型对前一帧图像目标定位的结果作为后一帧图像目标定位的初始位置,解决了主动形状模型难以确定初始位置的问题。
