【Abstract】 Face recognition is a challenging task in the area of pattern recognition and has potential prospect for applications in the future. This paper proposes an approach based on the discrete cosine transform (DCT) and neural networks, which extracts holistic and local DCT coefficients and feeds them to the multi-layer perceptron classifier. The experiment shows the approach achieves a balanced tradeoff between recognition rate and speed.更多还原
