ESTIMATED FACE GENERATION DEVICE, FACE COLLATION DEVICE, ESTIMATED FACE GENERATION METHOD, AND ESTIMATED FACE GENERATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To generate an estimated face by estimating, from a face image at a certain time point, a face image at the other time point.SOLUTION: An average face generation processing section 14c generates average face data 13a for each age group. An age difference vector calculation section 14d calculates an age difference vector 13b indicating a face change caused by aging from the average face data 13a of different age groups. An estimated face generation processing section 14e processes face image data while using the age difference vector 13b corresponding to the age group before and after processing, thereby generating estimated face data 13c estimating, from face image data at a certain time point, face image at the other time point. A collation processing section 14f executes face collation by using the estimated face data 13c as reference data.
