视频和图像处理：采用极几何的视频稳定化Video Stabilization using Epipolar Geometry
Amit Goldstein, Raanan Fattal 移动相机拍摄赏心悦目的流畅的视频序列是一项重要的任务，往往涉及使用相当复杂的解决方案。电影制作和广播室安装自己的相机轮式推车辊的轨道或使用steadicams的，这是手持式的机械稳定系统。通常情况下，小车轨道需要以特定的场景进行定制，需要时间来设置。在各种不同的情况下，这两种解决方案是不适用的，或没有提供足够的稳定。这激发了基于计算机的视频稳定算法的开发。Shooting pleasing smooth video sequences from a moving camera is a nontrivial task which is often dealt with using rather involved solutions. Film-makers and broadcasting studios mount their cameras on wheeled dollies that roll on tracks or use steadicams, which are hand-held mechanical stabilizing systems. Often, the dolly tracks need to be customized to the particular scene and take time to setup. There are various scenarios where both solutions are inapplicable or do not provide enough stabilization. This motivates the development of computer-based video stabilization algorithms.
