Abstract :
A face feature extraction system is proposed, based on previous works that utilize Gabor filters and self-organizing maps, but having the difference that we use a final stage consisting of a backpropagation network to improve the recognition. Besides this addition, we look forward to a more convenient place to locate the center frequencies of the filters, and also we apply a Fourier transformation to the self-organizing map output to get translation invariance in the feature map, before the backpropagation network
