I am doing my project in video analytics. I have to densely sample video. Sampling means converting video to spatio-temporal video volumes. I am using the python language. How can I do that in python? Is that option available in opencv or any other package? Input video sequence and desired output is shown

推荐答案

使用

cap = cv2.VideoCapture(fileName)

遍历每帧:

while(cap.isOpened()):

    # Read frame
    ret, frame = cap.read()

如果需要，您可以将每一帧插入3D矩阵中以获得所需的时空矩阵

If you want you can just insert every frame to a 3D matrix to get the spatio-temporal matrix that you wanted
