This paper addresses the automatic analysis of court-net sports video content. We extract information about the players, the playing-field in a bottom-up way until we reach scene-l...
Abstract. In this paper, we present a generic 3-D modeling for analyzing court-net sports videos, which enables to map points in the real-world coordinates to the image coordinates...
