Information processing device and method, program and recording medium for identifying a gesture of a person from captured image data

摘要

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.

1. An information processing apparatus, comprising:
circuitry that
captures an image of a human subject;outputs data indicative of a position of at least one joint of the human subject, the at least one joint being a place at which two parts of the human subject are joined;outputs, as a result, the captured image of the human subject and the output data by overlapping a plurality of points and lines indicative of the position of the at least one joint of the human subject on the captured image of the human subject; anddetermines a gesture of the human subject based on the output data.
