[Explanation]

1. In the ‘OpenCV’ library folder/example folder, there is a ‘WhichFace.pde’ file.

2. It reads a picture and recognizes a face in the picture.

3. As in the name of this program, it is necessary to distinguish a human face, but the face registration function or the identification function does not work well.

Have any of you ever used it? Is it working well?
