cv没有成员BackgroundSubtractorMOG [英] cv has no member BackgroundSubtractorMOG

问题描述

我是opencv的新用户，并按照说明安装它：
http://docs.opencv.org/doc/tutorials/introduction/windows_install/windows_install.html#windows-installation
我使用安装制作您从源文件自己的库，这工作很好（使用Visual Studio 2013）。我可以运行基本命令，如读取图像，写图像，运行边缘检测，视频处理等。
但现在我试图使用BackgroundSubtractorMOG，我得到的错误BackgroundSubtractorMOG不是cv的成员。最简单的代码如下，我不知道从哪里开始。我在安装中缺少什么？任何想法？

I am new to opencv and followed instructions to install it as described here: http://docs.opencv.org/doc/tutorials/introduction/windows_install/windows_install.html#windows-installation I used the section "Installation by Making Your Own Libraries from the Source Files", which worked well (using Visual Studio 2013). I am able to run basic commands, like read an image, write an image, run edge detection, video processing etc. But now I tried to use BackgroundSubtractorMOG and I get the error that BackgroundSubtractorMOG is not a member of cv. The simplest code is below and I don't know where to start. Am I missing something in my installation? Any ideas?

#include "stdafx.h"
#include<opencv2/opencv.hpp>

int main()
{
    cv::BackgroundSubtractorMOG bg;
    return 0;
}

推荐答案

with opencv3.0，BackgroundSubtractorMOG已移至 opencv_contrib repo

with opencv3.0, BackgroundSubtractorMOG was moved to the opencv_contrib repo

到使用剩余的BackgroundSubtractorMOG2或BackgroundSubtractorKNN，您必须使用：

to use the remaining BackgroundSubtractorMOG2 or BackgroundSubtractorKNN you'd have to use:

Ptr<BackgroundSubtractorMOG2> bgm = createBackgroundSubtractorMOG2(...);
