A new image database with five facial expressions (neutral, smile, anger, sadness, surprise) of 60 women was constructed using a conrputat-ionally efficient projection-based teclrnique. Fxperimental resiilts using the new database and an existing one (60 men) reveal that the new technique outperforms the standard vector matching technique and two recently developed methods using fixed-size and constructive one-hidden-layer neural networks. The mean recognition rate can be as high as 95% for the two databases." @default.
