Literature survey of automatic face recognition system and eigenface based implementation
MetadataShow full item record
There are three fundamental grounds for me to write this survey paper: the first is to provide an uptodate review of the existing literature, and the second is to reveal some technical term that how a Computer can recognize a Face (mostly the Algorithms) and the final intention to let know the beginners research opportunity and various prospect of face recognition field To provide a comprehensive survey, I started from the relevant psychophysical studies that how human being perform this work. Then move on to existing recognition techniques and present detailed descriptions of all techniques. In addition, I put some comparative studies between systems and tried to explain some preprocessing difficulty (illumination, pose variation, image quality etc.) and its explanation for face recognition system. Finally we tried to implement a AFR system based on Eigenface method where we have added a noise filtering .
