Then the methods of normalizing MV, weighted extended vector median (WEVM) filter on the MV fields and the existent segmentation results projection were utilized to obtain the moving mask of object.

然后采用运动向量归一化、噪声向量滤除、权值扩展向量中值（WEVM）滤波及前帧分割结果后向投影技术来得到对象的运动掩码；

It is possible to calculate a moving average by using the open, close, high, low or even the median.

移动平均线的计算可能选用开盘、收盘、高点、低点甚至是总价价格。
