Comparison Against Other Biometric Recognition Technologies – Why Face Recognition?
When we recognize whether the person in front of us is a family member, a friend, or someone else, or identify one of a pair of identical twins, or guess what someone feels about us, or suspect whether someone is telling a lie or hiding something, we are making split-second judgments of the other person’s facial expressions. We do this all the time, in everyday situations.
Our brains handle these judgments. But as the perceptual organs that feed the brain with information to support such judgments, eyesight is generally the most reliable of the five senses.
Therefore, face recognition is the most natural form of biometric recognition method for humans to practice. It is also the method most likely to deliver the best results in terms of both speed and accuracy.
