FACE RECOGNITION SYSTEM ROBUST TO ILLUMINATION CHANGE

摘要

PURPOSE: A face recognition system is provided to control misrecognition rates generated in an illumination change environment by applying a characteristic extracting technology based on image covariance. CONSTITUTION: A face database (DB) (150) stores face images and identification information for the face image. A face area detecting unit (110) extracts the face image from the inputted image, and a pre-processing unit (120) changes the pixel values of pixels constructing the face area into a binary pattern. A characteristic extraction unit (130) extracts characteristic information from the face image changed into the binary pattern. A face recognition unit (140) recognizes a face by using the characteristic information for the face images stored in the characteristic information and the face DB.
