如何从图像中减去背景 - python，opencv

Question

How to subtract the background in a still image? IF the issue is with videos then we can use cv2.createBackgroundSubtractorMOG() . I tried to manipulate the function, but I got AttributeError

This is what i have tried:

img = cv2.imread('lena.png')
fgbg = cv2.createBackgroundSubtractorMOG2()
fgmask = fgbg.apply(img)
cv2.imwrite('{0:d}.jpg'.format(i),fgmask)

But I got this error:

AttributeError: 'module' object has no attribute 'createBackgroundSubtractorMOG2'

Any suggestion are welcome!

Answer 1

fgbg = cv2.createBackgroundSubtractorMOG2()

在 opencv3 教程中不可用 - 您可以使用：

fgbg = cv2.BackgroundSubtractorMOG2()
