The system diagram above shows a fully automatic system for detection, recognition and model-based coding of faces for potential applications such as video telephony, database image compression, and automatic face recognition. The system consists of a two-stage object detection and alignment stage, a contrast normalization stage, and a Karhunen-Loeve (eigenspace) based feature extraction stage whose output is used for both recognition and coding. This leads to a compact representation of the face that can be used for both recognition as well as image compression. Good-quality facial images are automatically generated using approximately 100-bytes worth of encoded data. The system has been successfully tested on a database of nearly 2000 facial photographs from the ARPA FERET database with a detection rate of 97%. Recognition rates as high as 99% have been obtained on a subset of the FERET database consisting of 2 frontal views of 155 individuals.In September 1996, we participated in the final round of FERET tests administered by the US Army Research Laboratory which consisted of a large gallery test containing nearly 3,800 frontal images. Our system was found to be the top competitor (by a typical margin of 10% to the next best competitor). Also our system was the only fully automatic recognition system participating in the competition. The details of this competition and an analysis of the test results are available in this PostScript preprint.
