Applying Brain Waves to Face Recognition

The purpose of this research is to recognize The Human faces by analyzing the brain waves, detected by EEG, of subject. Initially, a subject looked at an image of human face until the subject remembered the facial features of the face. Then we carried out the EEG experiment. Each face used in the experiment was divided into three regions: eyes, nose and mouth, and two other faces were randomly selected. Totally, nine regions, three for each face, were randomly selected and shown on the monitor for the subject. Based on the collected brain waves, the amplitude of P300 signals achieved a significant difference between the regions of the remembered face and other two faces. In this way, a face by combining eyes, nose and mouth could be generated which is the same as the remembered face. We had succeeded recognize a human face by retrieving the brain waves after the subject watching at the facial regions. This is very useful to find out the criminal by the witness who was only required to watch the facial features.
