We have developed a very simple yet highly reliable face recognition method called VQ histogram method. A codevector referred (or matched) count histogram, which is obtained by Vector Quantization (VQ) processing of the facial image, is utilized as a very effective personal feature. By applying appropriate low pass filtering and VQ processing to a facial image, useful features for face recognition can be extracted. Experimental results show a recognition rate of 95.6% for 400 images of 40 persons (10 images per person), which contain variations in lighting, posing, and expressions, form publicly available ORL database. Equal Error Rate (ERR) of 2.6% is obtained for the verification experiment. By combining multiple low pass filtering procedures, the recognition rate increases up to 97% or higher.
