Abstract
Abstract A method classifies images of faces according to gender. Training images of male and female faces are supplied to a vector support machine. A small number of support vectors are determined from the training images. The support vectors identify a hyperplane. After training, a test image is supplied to the support vector machine. The test image is classified according to the gender of the test image with respect to the hyperplane.

A method for classifying images of faces according to gender, comprising the steps of: supplying a vector support machine with a plurality of training images, the training images including images of male and female faces; determining a plurality of support vectors from the training images for identifying a hyperplane; supplying the support vector machine with a test image; classifying the gender of the test image with respect to the hyperplane; and reducing the resolution of the training images and the test image by sub-sampling before supplying the images to the support vector machine; wherein the test image contains less than 260 pixels.
