thanks for the link. the code is OK except it needs only updating cvCaptureFromCAM -> cv::VideoCapture. i have compiled and tested with OpenCV 3.1 - Code::Blocks

Hi @sturkmen , I have changed capture = cvCaptureFromCAM( -1 );to `cv::VideoCapture( 0 ); still this erros displayed using opencv 2.4.10 :

   `C:\Documents\opencv\face\main.o:main.cpp|| undefined reference to `createCornerKernels()'

   'C:\Documents\opencv\face\main.o:main.cpp|| undefined reference to `findEyeCenter(cv::Mat, cv::Rect_<int>, std::string)'

you can try test.cpp i did some small changes and reformed the code in one cpp file ( tested with OpenCV 3.1 and OpenCV 2.4.12 )

note : sometimes fails to locate pupils

thanks very much for help , I tried plying video file but was not working , what should be changed to play video files

tofi ( 2016-01-20 15:27:09 -0500 )edit

it is ready to use with both webcam and videofiles

   // Read the video stream
  if( argc > 1)
  capture.open( argv[1] );
  else
    capture.open( 0 );

just run the program giving videofilename as an argument ( if you run on windows drag the videofile on the exe and drop)
