PiD, a person identification system using voice and face
USA Patent 5,412,738
The system is organized as a set of non-homogeneous classifiers
whose outputs are integrated after a normalization step. In
particular, two classifiers based on acoustic features and three based
on visual ones provide data for an integration module (see the papers
Automatic Person Recognition by Using
Acoustic and Geometric Features, R. Brunelli and D. Falavigna,
T. Poggio, L. Stringa and Person
Recognition Using Multiple Cues, R. Brunelli and D. Falavigna).
The system is also able to reject a stranger: its strictness can be
tuned to the application requirements.
