In this paper, we propose a new method for synthesizing player-view from multiple view videos in tennis. Our method is divided into two key techniques: virtual-view synthesis and player's view-point estimation. In the former technique, the existing method "view interpolation", which is a technique of synthesizing images in an intermediate viewpoint from the real images in two view-points,...
In this paper, we propose a new method to extract and calculate the 3D trajectory of a pitched baseball in a video clip. Compared to previous methods, which require video clips from multiple view points, only a single-view television clip is required for our method. Since global search methods based on dynamic programming are used to find the trajectory of the ball, the system is more robust than...
We present a new video browsing method for multiple videos that are taken at large-scale space for live 3D events such as soccer games. By our method, multiple viewers over a computer network can browse a live 3D event from any viewpoint and each viewer can move his/her viewpoint freely. Our algorithm consists of five steps. Our system first captures videos from multiple cameras, then extracts texture...
