A face recognit ion m ethod based on m ult-i m odal parts and principa l com ponent analysis ( MM P-PCA ) was adopted. Im age preprocessing m ethods for variou s input dev ices, such as geom etric nor- m a lizat ion, g lasses rem oval and grayscale norm alization on a reg ion o f in terest ( RO I) w ere em ployed to mi prove the perform ance of the system. Expermi ental resu lts on a real database proved that th is authentication system can a- ch ieve acceptab le resu lts for recogn ition even though the reso lut ion o f the mi age is quite low and the illum ination is uncontro lled. B ecau se of the ex tensive app lication of 2G- ID card in public security, cu stom s, banking and other ar- eas, the proposed face authen ticat ion system u sing 2G-ID card has great pract ica l value.
