An image database system for storing facial images for a plurality of people together with related attribute information to enable searching and retrieving required facial images based on the related attribute information, said image database system comprising:

• a face dictionary for storing facial image information together with attribute information corresponding to the facial image information;
• and
• a processor for comparing a facial image stored or to be stored in the image database with the facial image information stored in the face dictionary,
• wherein, when the facial image information matching the facial image exists in the face dictionary, said processor stores the attribute information, which is stored in the face dictionary corresponding to said matching facial image information, in the image database as related attribute information of the facial image.

A computer-executable program for compiling an image database in which facial images for a plurality of people are stored with related attribute information to enable searching and retrieving required facial images based on the related attribute information, said program comprising:

• instructions for storing facial image information together with attribute information corresponding to the facial image information in a face dictionary;
• and
• instructions for comparing a facial image stored or to be stored in the image database with the facial image information stored in the face dictionary;
• wherein, when the facial image information matching the facial image exists in the face dictionary, the attribute information, which is stored in the face dictionary corresponding to said matching facial image information, is stored in the image database as related attribute information of the facial image.

A computer-readable medium having computer-executable instructions recorded thereon for compiling an image database in which a facial image of a person is stored with related attribute information to enable searching and retrieving required facial images based on the related attribute information, said instructions comprising:

• a first set of instructions for storing facial image information together with attribute information corresponding to the facial image information in a face dictionary;
• a second set of instructions for comparing a facial image stored or to be stored in the image database with the facial image information stored in the face dictionary;
• and
• a third set of instructions for storing, when the facial image information matching the facial image exists in the face dictionary, the attribute information, which is stored in the face dictionary corresponding to said matching facial image information, in the image database as related attribute information of the facial image.
