Patent ID: 8542928

Claim:
An information processing apparatus comprising: an input device adapted to input image data containing a face; a memory adapted to store the image data; a first detection device adapted to detect, from the image data stored in said memory, positions of a plurality of specific parts of the face, wherein said first detection device has been learned by supervisory data with various kinds of variations; an area setting device adapted to set respective feature point pixel extraction areas for a plurality of feature point pixels of the specific parts in the image data on the basis of the detected positions of the specific parts; a second detection device adapted to detect respective positions of the plurality of feature point pixels of the specific parts from the respective feature point pixel extraction areas, wherein said second detection device has been learned by supervisory data with specific variation that is one of the various kinds of variations; and a determination device adapted to determine facial expression of the face on the basis of the detected feature point pixels, wherein said second detection device has higher detection accuracy than detection accuracy of said first detection device, and said first detection device is robust to a variation in a detection target.
