I'm using opencv to grab images from webcam .but all images are grey !
I tested opencv 2.2 & 2.3 with my A4tech webcam and Microsoft Lifecam but the screen is still grey !
I'm using VIsual Studio 2010 Express
My code is very simple :
int main(int argc, _TCHAR* argv)
I'm currently using the C# wrapper, EmguCV, that encapsulates OpenCV. If I weren't, I'd be able to jump right in and help, as I'm playing with facial recognition right now. However, not using the straight OpenCV. My applications are currently interfacing with a ip-camera, getting greyscale output. If you are still having problems in a couple days of playing with this, I'll try and install the base OpenCV and give it a try -- and help you.
