I rebuild 3.1.0 library and again has got a lot of faces on both my books (with Intel HD 4000 one and NVIDIA GeForce GT 425M another) captureFrame=640x480 ; type=16 faces.size()=18446743934142353947 after

capture >> frame; std::cout << "captureFrame=" << frame.cols << "x" << frame.rows << " ; type=" << frame.type() << std::endl;

    std::vector<cv::Rect> faces;
    face_cascade.detectMultiScale(frame, faces, 1.1, 3, 0 | CV_HAAR_SCALE_IMAGE, cv::Size(30, 30));
    std::cout << "faces.size()=" << faces.size() << std::endl;

What are we all doing wrong?

@sturkmen I have the same trouble with igdfcl64.dll. Latest drivers are installed. Is there a known solution to this problem? HP Elitbook Folio9470m Windows 10 x64

I rebuild 3.1.0 library. Tried both detect_blob.cpp and facedetect.cpp. They do not work. Project with facedetect.cpp generate an error "Exception thrown at 0x00007FFF22E36533 (igdfcl64.dll) in OCV310.exe: 0xC0000005: Access violation writing location 0x00000000A8F8B690." at line number 3579 in file ocl.cpp with code retval = clBuildProgram(handle, n, (const cl_device_id*)deviceList, buildflags.c_str(), 0, 0);

2016-04-19 16:05:45 -0500 asked a question How to build OpenCV 3.1.0 from github in Visual Studio 2015 x64 Windows10

Hi Guys!

Please tell me how to build OpenCV 3.1.0 from github in Visual Studio 2015 to x64.

I used git clone https://github.com/Itseez/opencv.git

and then use Cmake with default setting

after that in Visual Studio there is only one Ğ°ctive platform - Win32 without any other options.

So after building we can see only x86 directory in install directory.

I tried also make a new platform - x64 and then during building error LNK1112 appears.

Maybe is anywhere guide how to do it?

I try detect_blob.cpp. It works. Yes, i going to rebuild tomorrow. Now is night here in Russia :( Bye! See you late!

May be problem is in precomiled libs. Here is describe step by step: http://dogfeatherdesign.com/opencv-3-.... Sorry offtop, this about 3.0.0

2016-04-18 15:16:52 -0500 commented question Detectmultiscale for face detection in opencv 3.1 C++ doesn't work properly

@sturkmen i tried your code above in 3.0.0 and it don work properly. There is access violation error at size < 462. (At size >462 faces.size=0). And also, you are using LBP cascade and CV_HAAR_SCALE_IMAGE key. Is it correct?

2016-04-18 13:48:53 -0500 commented question Detectmultiscale for face detection in opencv 3.1 C++ doesn't work properly

@sturkmen No, I did not build the library. I used ready-made from opencv3.1.0\opencv\build\x64\vc14\lib

Hi! I have some problem on Visual Studio 2015 Community, C++, Windows 10, OpenCV 3.1, x64, tried both Debug and Releas. Source code like above. I tried various combinations of the debug configurations: MT, MD, MDd I tried all of classifiers for faces: haarcascade_frontalcatface.xml, haarcascade_frontalface_alt.xml, haarcascade_frontalface_default.xml from opencv\build\etc\haarcascades

When I tried source line

face_cascade.detectMultiScale(frame_gray, faces, 1.1, 3, 0 | CV_HAAR_SCALE_IMAGE, Size(30, 30));

the error access violation record appears ('record' or 'writing' i do not shure because have a Russian interface)

Next I tried change Size(500,500), and when line pass but faces keeps billlllions of faces:

I have the same problem - innumerable number of faces in face_cascade.detectMultiScale.

Visual Studio 2015 Community, C++, Windows 10, OpenCV 3.1, x64, tried both Debug and Releas. Source code like above.

I tried also sample code from opencv\sources\samples\cpp\facedetect.cpp it do not work too, but it is an another story.
