PROBLEM TO BE SOLVED: To solve the problems that there are many restrictions of a photographing condition or the like at the time of estimating an individual from the feature vector of a face image or the like and there are the restrictions of a walking place or the like at the time of estimating it from the pressure distribution of the shoe sole of the individual and footsteps, etc. SOLUTION: In preprocessing 1, a background is removed from an input moving image frame. In individual area extraction processing 2, the circumscribing graphic of an individual area is obtained from respective frames and a circumscribing graphic parameter for defining the shape of the circumscribing graphic and a position inside the frame is calculated. In individual attribute feature vector extraction processing 3, the walking action characteristics and walking time sequence characteristics of the individual in input moving images are calculated from the time sequence of the circumscribing graphic parameter of the respective frames and an individual attribute feature vector for indicating the attribute of the individual is calculated from the characteristics. In identification processing 4, the human attributes are estimated by the vector collation process of collating the individual attribute feature vector with a reference vector prepared from moving images for learning. |
