Patent ID: 8437507

Claim:
An information processing device, comprising: a learning image input unit configured to input a learning image, in which a tracked object is captured on different shooting conditions, together with the shooting conditions; a feature response calculation unit configured to calculate a response of one or more integrated features, the integrated features being obtained by at least partially overlapping a shape feature and a color feature of the tracked object, with respect to the learning image while changing a parameter, the parameter defining at least one of a position on the learning image, a size, and an angle of the integrated features, in accordance with the shooting conditions; a feature learning unit configured to recognize spatial distribution of the one or more integrated features in the learning image based on a calculation result of the response and evaluate a relationship between the shooting conditions and the parameter and a spatial relationship among the integrated features so as to learn a feature of the tracked object; and a feature storage unit configured to store a learning result of the feature.
