I suggested a db modification in the mailing list that Marcel approved because
it was backwards compatible. I think it is suitable for the classifier purpose.

It consists of two new tables: faces and imagefaces.
Faces --> faceid, tagid.
Imagefaces --> imageid, faceid, x1, y1, x2, y2

The faces table is used to match a face with a tag in the database. The other
one should be directly written by the classifier. Once you have a trained
classifier, it'll first will detect faces in an image. The second step is to
assign a different faceid to each different face.

I'd really like to be a part of this, but currently I don't have time.

About the performance of the algorithms, don't be too optimistic. It will be
very difficult to recognise ocluded faces. Reducing the number of false
positives is easier.
