Gender classification with support vector machines
View Patent ↗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.
1. 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.
