<P>PROBLEM TO BE SOLVED: To provide a person attribute estimation device and the like capable of accurately estimating person attributes from a face image. <P>SOLUTION: A wrinkle feature amount, a spot feature amount and a lip feature amount in a face area are calculated as feature amounts for estimating person attributes. The spot feature amount is calculated for each block using a difference between an image after mask processing with a skin mask and a blurred image obtained by further performing smoothing processing thereof. As the wrinkle feature amount, the intensity and direction of a wrinkle are calculated for each block from the image after mask processing with the skin mask. The lip feature amount is calculated for a lip area extracted using the skin mask as a color comparison value with respect to a reference color in the original face area. By using the spot feature amount, the wrinkle feature amount and the lip feature amount calculated in this way, person attributes such as age and sex can be accurately estimated, and robustness against environmental variation can be improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
