Face recognition with openCV - compare faces
hi,
I've been looking into the amazing world of openCV for a coming little project of mine. I've managed to track my face using the webcam and do some of the other operations that opvenCV provides. I would like to be able to take one and only one snapshot of each different face that is detected. So I am trying to work out a way to tell whether the tracked face has been captured before or not. Is there a way with openCV to compare two faces and figure out whether it's the same person or not? Something tells me that this is not a straight forward task and requires some advanced deep learning magic, but I'd be curious to hear any thoughts.
thank you
Answers
Most of the Processing and intro-to-OpenCV examples are face detection (is it a face?) not face recognition (which face is it?).
For recognizing specific faces:
Without openCV, Rekognition API -- https://forum.processing.org/two/discussion/9593/opencv-and-face-recognizer -- https://github.com/shiffman/Rekognition-for-Processing
... See also examples from his Face-It workshop: https://github.com/shiffman/Face-It
I'm not sure about mapping from processing, but OpenCV definitely does face recognition:
yeah I came across the opencv links last night, which I think it's beyond processing. (One day I need dive into c++ and OF)
The Rekognition-for-Processing seems somewhat interesting. I may give that a go. I guess the question is whether it's possible to recognize faces while it is training at the same time. Or whether one image is enough for a very basic train.
thanks for all the links, I really appreciate
Hope it helps!
That's a fundamental problem for facial recognition algorithms of all kinds. If you aren't backed by some training data (whether from a web service or locally) then performance may be very poor. The best thing is to test and see how well it performs.
True true... Maybe it's a good time to also look into those multi-threading sketches. =]
oh noooo.... Got back home and ready to try Rekognition-for-Processing, but apparently it needs an API key and unfortunately it seems they don't give them out any more

looking for similar libraries
There is this one that may get me there

please help me out... i am also stuck at the same point
