Yahoo: Tessera one more time announced its FotoNation FaceRecognition. Tessera acquired Fotonation at the beginning of 2008 for $29M (plus another $10M if some goals are met). By that time Fotonation already had face recognition product for sale.
I guess this announcement relates to an improvement version of it, although it's not clearly stated. The technology appears to be software based and available for a number of platforms, including COACH and ARM. No recognition speed or number of simultaneously recognized faces is mentioned, both being very important merits of the algorithm.
