Abstract:
1. An information processing device comprising: an image capturing device configured to capture a movement of an object within a moving image; a tracking processing unit configured to define a candidate curve representing a contour of an object in a current image frame included in the moving image captured by the image capturing device, based on a contour of the object estimated in an image frame at a preceding point of time, and to estimate the contour of the object in the current image frame by observing the likelihood of the candidate curve; a gesture detection unit configured to acquire a parameter indicating an orientation of the object or a position of the object by performing image analysis in an area inside the contour of the object estimated by the tracking processing unit, and determine whether a gesture is made by checking a time-dependent change in the orientation of the object or in the position of the object, which is estimated from the parameter, by referring to a criterion defined for each gesture; and an output data generation unit configured to perform, when the gesture detection unit determines that a gesture is made, a process corresponding to the gesture and generate output data accordingly.
