Abstract

This paper presents a new augmented-reality system designed to generate visual enhancements for TV broadcasted court-net sports. A probabilistic method based on the Expectation Maximization (EM) procedure is utilized to find the optimal feature points, thereby enabling the automatic acquisition of the camera parameters from the TV image with high accuracy. A virtual camera derived from the original camera, helps to synthesize a variety of virtual scenes, such as the scene from the viewpoint of a player, depending on the intention of the user. To preserve the visual nature of the original human motion, the player's shape and texture are extracted from the real video and texture-mapped onto the virtual video. The system was tested over a set of court-net sports videos containing tennis, badminton and volleyball and demonstrated promising results.
