Abstract
A method identifies an unknown face in an input image using reference images of known faces. A Haar-like feature vector is extracted from each image. The vectors are compressed. An L1 norm is determined between the compressed feature vector of the input image and each compressed feature vector from the set of reference images to determine a most similar reference image. The identity of the face associated with the most similar reference image is assigned as the identity of the unknown face in the input image.
Claims12
A method for comparing an input image of an unknown face with a reference image of a known face, comprising the steps of:
- extracting a feature vector from each image;
- compressing the feature vectors into compressed feature vectors;
- and
- comparing the compressed feature vectors to determine a similarity score for the two faces.
