web cam and cubieboard

Well I'm back again with the computer vision, now with a webcam

The idea is to how fast is our cubieboard to do some exercise, as could be detect faces, or detect and object.

I've saved a couple of videos in different resolutions, they are saved from my desktop and you can see how the lag is working, it's not realistic exercise, but it can show as a little information.

First the code

#define WITH  640
#define HEIGHT 480

int main (int argc, char** argv)
{

Mat img;
bool salir=false;
double flagGrab,flagRetrieve, flag;


VideoCapture webCam(0);
//Change the size of the resolution (640x480,320x240,160x120)

    webCam.set(CV_CAP_PROP_FRAME_WIDTH,WIDTH);
    webCam.set(CV_CAP_PROP_FRAME_HEIGHT,HEIGHT);
    while ( waitKey(1) <= 0 && !salir)
    {
        flag=getTickCount();
        webCam.grab() ? :salir=true;
        flagGrab=getTick(flag);

      
        flag=getTickCount();
        webCam.retrieve(img);
        flagRetrieve=getTick(flag);
//here the code will start to work with the image
        imshow("Web Cam",img);

    }
return 0;
}

and here the result, the videos are a little bit bored

640x480

320x240

160x120

With this videos I'll try to make the exercise to detect a pattern, on a real time detection.
