The faces are presented under a wide variety of conditions to the system, and the classification performance is measured. The system is trained by gradually adapting photorefractive holograms.Optical Pattern RecognitionNeural NetworksPhotorefractivesNeural NetworksPhotorefractive HologramsAlgorithmMemorytext::journal::journal article::research article
