Patent ID: 8676740

Claim:
An age estimation system, having a processor, and a memory storing instructions to be executed by the processor, that estimates an age based on at least one piece of input data, wherein the ages are separated into a plurality of classes, each indicating a predetermined age group, the system comprising: a first estimation unit which includes at least one first feature extraction unit which extracts at least one first feature from said input data, and which estimates said age as a discrete quantity based on said first feature; a second estimation unit which includes at least one second feature extraction unit which extracts at least one second feature from said input data, and which estimates said age as a continuous quantity based on said second feature; a score-generation unit which generates a score, which is a function indicating a relation between respective estimated results of said first estimation unit and estimated results of said second estimation unit, and age; an integration unit which outputs an estimated age based on a score obtained by integrating a score of an estimated result of said first estimation unit and a score of an estimated result of said second estimation unit.
