Claim One:
1. An age estimation apparatus for estimating an age of an object contained by an image data, the age estimation apparatus comprising: a processor configured to control any of a dimension compression unit and an identification unit; the dimension compression unit configured to output low dimensional data of image data by applying a dimension compression to the image data by extracting a feature from the image data; and the identification unit configured to minimize a value of a predetermined function, to set a learned parameter for determining an age bracket in which an error of an estimated age is minimized, and to estimate the age using the learned parameter, wherein the age is estimated from a feature which is contained in the low dimensional data, the error is calculated between the estimated age and a correct age, the predetermined function is defined by the error, the learned parameter is set by a weighting function which is a function of the age bracket, the correct age being the age of the object contained by the image data, the weighting function is defined on the basis of a standard deviation of each of a plurality of perceptual ages, and the identification unit is further configured to estimate the age to closely match a human recognition result.
