For the records: taking a look at core/src/matrix.cpp it seems that, indeed, the constructor cv::Mat(IplImage*) has disappeared.

But I found this alternative:

    IplImage * ipl = ...;
    cv::Mat m = cv::cvarrToMat(ipl);  // default additional arguments: don't copy data.

Hi,

I'm having problems porting some legacy code to OpenCV 3.X (git master), because can't find any replacement for this kind of conversions:

    IplImage * ipl1, *ipl2;
    // ...
    const cv::Mat m = cv::Mat(ipl,false);  // Fails 
    cv::Mat  m2 = ipl2;  // Fails

Have all those constructors been removed from the new OpenCV 3.X for some reason? Are there any alternatives?

Thanks.

The changes were integrated into the main OpenCV repo via a pull-request, so I removed my fork. Here's the pull request: https://github.com/Itseez/opencv/pull/1653/commits

This specific error can be fixed by changing that line to:

obj.info()->addParam<FeatureDetector>(obj, "detector", obj.detector, false, 0, 0, "Detector algorithm.");

But there're a few other errors (and nasty internal compiler errors!) that have to be handled while building OpenCV in MSVC 2013. I uploaded the list of corrections to this fork of OpenCV in GitHub. --> pull request
