then, what i need to do?

actually i had copy the coding and change it a little bit and i am the beginner in using opencv.. anything wrong in my coding?

it dont has any error but it only display and play the video..coding for background subtraction doesnt take place..

i had done with the step, but it continue gives me some errors:

Error   9   error LNK1120: 7 unresolved externals   
Error   8   error LNK2019: unresolved external symbol "int __cdecl cv::_interlockedExchangeAdd(int *,int)" (?_interlockedExchangeAdd@cv@@YAHPAHH@Z) referenced in function "public: void __thiscall cv::Ptr<class cv::BackgroundSubtractorMOG>::release(void)" (?release@?$Ptr@VBackgroundSubtractorMOG@cv@@@cv@@QAEXXZ)
Error   3   error LNK2019: unresolved external symbol "public: __thiscall cv::_InputArray::_InputArray(class cv::Mat const &)" (??0_InputArray@cv@@QAE@ABVMat@1@@Z) referenced in function "void __cdecl processVideo(char *)" (?processVideo@@YAXPAD@Z)

When I delete that part, it will gives me a lot of errors: error C2039:'apply' : is not memeber of 'cv::BackgroundSubtractorMOG' error C3861: 'createBackgroundSubtractorMOG':identifier not found intelliSense: class "cv::BackgroundSubtractorMOG" has no memeber "apply" IntelliSense identifier "createBBackgroundSubtractorMOG" is undefined

may i have a right coding without any error?

i had tried to run but i get this error:

error C2601: 'detectAndDisplay' : local function are illegal

what i should do?

it is for c++?

I am a beginner for the openCV and VS. So, I need a help to give me the sample of coding for face detection using Viola Jones algorithm by using OpenCV and VS2013. Can someone help me please. Thanks..

I am the beginner for the opencv and c++. I had ran my coding.

It produce errors such as:

IntelliSense: "BackgroundSubtractor" is ambigious
IntelliSense: identifier "createBackgroundSubtractorMOG" is undefined
IntelliSense: class "cv::BackgroundSubtractor" has no member "apply"

I really need helps for my project. Thanks.
