Add heartbeat detection to verify the person is alive. [1] has one example, Google "use webcam to detect heartbeat" to find more. [1] https://github.com/thearn/webcam-pulse-detector

This was something I had to find out the hard way in the process of writing this https://github.com/thearn/webcam-pulse-detector Without interpolative resampling, it didn't work well for me at all.

I use OpenCV for reading and writing real-time video streams (like webcams or video frames) for my hobby computer vision projects, but tend to use other ML or image-specific libraries for actual processing. The cascade classifiers in OpenCV are okay, but it isn't too difficult to set up something comparable in scikit-learn that is more modern and robust. Though a bit less performant if you do need real-time response though. Best example that I have is a pulse rate detector that I put together, that uses OpenCV for video frame extraction & display but bare numpy/scipy for the rest. https://github.com/thearn/webcam-pulse-detector

For this purpose, MIT's Eulerian Video Magnification is next to impossible when you have both color changes and large motions (it is better suited to magnifying small motions, or subtle color changes in unmoving patches). NASA Glenn's thearn has developed another approach which has the same problems (https://github.com/thearn/webcam-pulse-detector). We developed our own solution, involving (among other things) pixel-accurate facial feature detection and filtering methods not subject to FFT's regularity assumption

If the camera works well, real-time biometrics are definitely a possibility: https://github.com/thearn/webcam-pulse-detector

Probably what will matter is not just detecting your face, but what you do with that, like https://github.com/thearn/webcam-pulse-detector Anyway, would go a bit forward into computer vision/opencv, not just face detection, but body/objects detection using that information to build things.

I have the same problem and have opened an issue: https://github.com/thearn/webcam-pulse-detector/issues/1 Maybe somebody that knows more about OpenCV than I do can figure out what's wrong.
