| Abstract(in English) | In conventional methods of object tracking, the position and posture of the object are estimated from their appearances in the image. However, those appearances cannot be obtained when the object is occluded by others. Moreover, the appearances that directly describe the posture of a spherical object like a ball cannot be obtained as image features though it is often tracked in a sportscast. Object's motion is the physical phenomenon in which object's states including its position and posture change from moment to moment. Although the position and the posture of an object have independent degrees of freedom, they influence with each other when the object is in move. Using this relation, it is possible to estimate one of them from the other. In this article, we introduce a model of object motion, which describes how the position and posture change with respect to time by physical laws of motion for estimating the position or posture invisible in the image sequence from visible ones. |
