python-2.7 - GMG无法在Open CV 3.0中运行

Question

我一直在尝试在新的Open CV版本Open CV 3.0中进行背景减法。我在Open CV 3.0和python 2.7中练习BackgroundSubtractorGMG。我在BackgroundSubtractorGMG上尝试代码。错误提示:

File "background.py", line 10, in fgbg = cv2.createBackgroundSubtractorGMG() AttributeError: 'module' object has no attribute 'createBackgroundSubtractorGMG'

我该如何解决这个错误？感谢您的关注和帮助，谢谢:-)

Answer 1

一旦构建了opencv以及opencv_contrib存储库:

>>> help(cv2.bgsegm)
Help on module cv2.bgsegm in cv2:

NAME
    cv2.bgsegm

FILE
    (built-in)

FUNCTIONS
    createBackgroundSubtractorGMG(...)
        createBackgroundSubtractorGMG([, initializationFrames[, decisionThreshol
d]]) -> retval

    createBackgroundSubtractorMOG(...)
        createBackgroundSubtractorMOG([, history[, nmixtures[, backgroundRatio[,
 noiseSigma]]]]) -> retval

换句话说，使用:

gmg = cv2.bgsegm.createBackgroundSubtractorGMG()
