Real-time dynamic scene modeling and rendering

想象一下，你正坐在客厅里观看一场现场直播的NHL比赛。你有一个巨大的屏幕和环绕立体声系统，这让你感觉好像你是在溜冰场边。在某些方面，这可能比在溜冰场观看比赛更好——你可以在去喝一杯的时候暂停比赛，回来的时候继续比赛，这是可能的，因为新的电视系统可以在本地存储信号，并在你需要的时候播放。然而，你难道不想拥有控制视角的自由，这样你就可以从自己喜欢的位置观看比赛，甚至在有人得分时冻结动作，从不同的角度重放场景吗？拟议的研究计划旨在使这成为下一代电视系统的现实。

Imagine that you are sitting in your living room watching a live NHL game. You have a giant screen and a surround sound system, which make you feel as if you are rink-side. In some aspects, it may be better than watching rink-side -- you have the freedom to pause the game when you go for a drink and resume when you return, which is possible because newer television systems can locally store the signals and play them when you want. However, don't you also want to have the freedom to control your viewpoint so that you can watch the game from your favorite spot, or even freeze the action when someone scores and replay the scene from different perspectives? The proposed research program aims at making this a reality for the next generation of television systems.
