I am trying to compile the facedetect.cpp in the OpenCV\Samples\C folder, in Visual Studio 2010. The project compiles and begins just fine, shows a preview of my camera, and then seems to crash at cascade.detectMultiScale() as soon as it detects a face. I concluded that OpenCV thinks I am too ugly.

Unhandled exception at 0x100342bf in HeadTrackerExample.exe: 0xC0000005: Access violation writing location 0x00000000.

Unfortunately the debug info doesn’t let me probe deeper. I am linking against cv210.lib;cxcore210.lib;highgui210.lib; the debug versions won’t work:

LDR: LdrpWalkImportDescriptor() failed to probe D:\OpenCV2.1\bin\cv210d.dll for its manifest, ntstatus 0xc0150002

I’m going to try to trick the classifier with a printout of Anne Hathaway but I am open to other suggestions.

    I spent the day trying to fix this. Who knows why it was crashing? I couldn’t link to the debug DLLs so we’ll never know. I downloaded the OpenCV-2.1.0-win32-vs2008.exe distribution. And I am using Visual Studio 2010. Therefore, the exe was crashing with

    LDR: LdrpWalkImportDescriptor() failed to probe D:\OpenCV2.1\bin\cv210d.dll for its manifest, ntstatus 0xc0150002
    Debugger:: An unhandled non-continuable exception was thrown during process load
    The program '[5172] HeadTrackerExample.exe: Native' has exited with code -1072365566 (0xc0150002).

    This is the “0xc0150002 error”. According to Dependency Walker, the OpenCV debug DLLs are trying to find msvcr90d.dll and msvct90d.dll, the Visual Studio 2008 debug runtime DLLs. Well, I obtained these and it still didn’t work, so then this gets into esoteric Windows sidebyside and manifest stuff.

    I switched to the OpenCV-2.3.1-win-superpack.exe distribution and it is now working.
