FaceOnIt is a robust, fast and powerful software library to find faces in pictures and videos. The library can be freely downloaded for non-commercial use (a free registration is required).
In addition to the library, two Windows demos are provided, in binary and source code forms:
- Face Detector detect faces in an image
- Face Tracker detect faces in live video (using your webcam or a similar video capture device)
Note: When an image bigger than the screen is loaded in Face Detector, the image is resized when displayed, but not during the face detection. The demo also use a different minimum possible face width on big images than on smaller ones, to speedup the process.
