Abstract

Official abstract text for this publication.

An image including a face is input (S 201 ), a plurality of local features are detected from the input image, a region of a face in the image is specified using the plurality of detected local features (S 202 ), and an expression of the face is determined on the basis of differences between the detection results of the local features in the region of the face and detection results which are calculated in advance as references for respective local features in the region of the face (S 204 ).

First claim
