Abstract: A method and apparatus for tracking an object, and a method and apparatus for calculating object pose information are provided. The method of tracking the object obtains object feature point candidates by using a difference between pixel values of neighboring frames. A template matching process is performed in a predetermined region having the object feature point candidates as the center. Accordingly, it is possible to reduce a processing time needed for the template matching process. The method of tracking the object is robust in terms of sudden changes in lighting and partial occlusion. In addition, it is possible to track the object in real time. In addition, since the pose of the object, the pattern of the object, and the occlusion of the object are determined, detailed information on action patterns of the object can be obtained in real time.

Abstract: A method and apparatus for performing registration of medical images includes mapping a virtual coordinate system used by a first medical apparatus and a virtual coordinate system used by a second medical apparatus to one another. The coordinate systems are associated with a real-time medical image captured by the first medical apparatus and a three-dimensional (3D) medical image previously captured by the second medical apparatus, respectively. The method further includes detecting a position of a probe of the first medical apparatus from a coordinate system used by the second medical apparatus, based on a result of the mapping, determining a volume image corresponding to the detected position of the probe from the previously captured 3D medical image, and extracting from the determined volume image a cross-sectional image corresponding to the real-time medical image, where the real-time medical image changes according to a patient's physical movement.
