<P>PROBLEM TO BE SOLVED: To provide a face meta-data generation technique for extracting face characteristic quantity for face recognition hard to be affected by a local error with compact description length. <P>SOLUTION: An area cutting means 121 cuts a local area of a facial image, a frequency characteristic extracting means 122 extracts a frequency spectrum in the local area, and a vector projecting means 123 projects an obtained frequency characteristic to partial space, thereby extracting a facial characteristic in the local area. The facial characteristic is generated as extraction face meta- data for a plurality of local areas with a changed cutting position. <P>COPYRIGHT: (C)2004,JPO |
