Information processing device and method, program and recording medium for identifying a gesture of a person from captured image data
First Claim
1. An information processing apparatus, comprising:
- circuitry configured to;
obtain, using an imaging device, an image of at least a part of a human subject;
estimate a position of a joint of the human subject based on the obtained image, the joint being a place at which two parts of the human subject are joined;
output, using a plurality of points and lines indicative of the estimated position of the joint, data indicative of the estimated position of the joint of the human subject as an estimation result; and
estimate a posture of the human subject based on the output data.

Abstract
An information processing device includes: an outline extraction unit extracting an outline of a subject from a picked-up image of the subject; a characteristic amount extraction unit extracting a characteristic amount, by extracting sample points from points making up the outline, for each of the sample points; an estimation unit estimating a posture of a high degree of matching as a posture of the subject by calculating a degree of the characteristic amount extracted in the characteristic amount extraction unit being matched with each of a plurality of characteristic amounts that are prepared in advance and represent predetermined postures different from each other; and a determination unit determining accuracy of estimation by the estimation unit using a matching cost when the estimation unit carries out the estimation.

8. A method, comprising:
-
obtaining, using an imaging device, an image of at least a part of a human subject; estimating, using circuitry, a position of a joint of the human subject based on the obtained image, the joint being a place at which two parts of the human subject are joined; outputting, using a plurality of points and lines indicative of the estimated position of the joint, data indicative of the estimated position of the joint of the human subject as an estimation result; and estimating a posture of the human subject based on the output data.
