1。访问在任何需要的帧所需像素

2。执行像素逐相对于第一帧帧差分像素

3。申请分类阈值

4。执行像素按有关透水框架像素帧差分

5。结合阈值的像素结果由像素帧差分-1. Access any desired pixel in any desired frame

2. Perform pixel-by-pixel frame differencing with respect to the first frame

3. Apply classification thresholds

4. Perform pixel-by-pixel frame differencing with respect to pervious frame

5. Combine the thresholded results of the pixel-by-pixel frame differencing
