| 1. | Also an algorithm which combines both model matching and feature matching is put forward . the algorithm uses the object contour in previous frame as the reference template of current frame . based on the fact that object has a continuous track in movement , object ’ s current position can be predicted based on previous position and then match the reference template around the predicted position
该算法将前一帧目标轮廓作为当前帧的参考模板,根据目标在运动过程中具有轨迹连续性的特点,利用目标过去的跟踪点位置信息得到当前的预测位置点,然后在预测位置点周围一定范围内进行模型匹配,以与参考模板匹配值最大的轮廓作为当前帧的目标轮廓,并且把它更新作为下一帧的参考模板。 |
