Frank,

Nice update on your project. Good to see that you are jumping into the Pi side of things and getting your feet wet. That is something that I should get started on sooner than later.

I look forward to hearing more on your project and your progress.

Frank,

You seem to be making good progress, it is only a matter of time and training before it will be (almost) correctly recognising you and the doll.

I have used a web based face recognition demonstration system before which was amazing good so I'm sure you'll get it going. Either that or you are a Cone Head!

Hi Frank,

This is great to see, you're getting good results!!

Very cool that you did this with the Python API. I've never tried this with OpenCV, I'm a beginner with it, and had an easier task to just identify humans (not individuals). I used very low-res images, so that did help speed things up as you suggest. In your case there's a limit of course, since you still need face area detail, and it's a wide-angle lens.

I guess if the training content is dozens or hundreds of images then it will provide even more accuracy, and also perhaps for the intended application, a voting system could be used, e.g. it waits for the results from a dozen frames from the video, and then adds up the results, to get a percentage probability that it was you or the doll, and then acts if the result is (say) 70% likely, otherwise reattempts from the next dozen frames.

One other idea could be to double-check how other sources online may have implemented such recognition in OpenCV, because some people may have implemented differently (e.g. data-reducing or filtering or other manipulation procedures in a different order). I had to try different combinations to get something working enough to get moving forward.

Anyway, it's really great that the system is in principle already working and now just needs tweaks.
