Face Recognition on the iPhone
I am using OpenCV for my iphone app.
I want to know how i can detect the face in the image and after that i want to compare it with other faces to know how is the person in the photo?
is it possible with OpenCV?
Possible yes… But it would only work at certain angles, and would need some massive coding from your part anyway..
Also, iPhone probably would run that VERY, VERY, VERY slow! (I mean, trying to match 1 person with a database of 100 photos would probably take some hours already)
