hdr for video? The work presents a system for automatically producing a wide variety of video enhancements and visual effects. Unlike traditional visual effects software (e.g., After Effects, Shake, Boujou, etc), the system is completely automatic and no manual labor is required from the user. The major limitation of the work is that it can currently handle only videos of static scenes (i.e., videos shot with a moving camera but containing no moving objects in the scene). Efforts are being made to lift this restriction in future work. Applications of the system include: High resolution/definition video, High dynamic range video, Removing objects from a video, Creating painterly (NPR) videos, Video stabilization, Easy video editing Project website: grail.cs.washington.edu/projects/videoenhancement/videoEnhancement.htm
Keeping two or more copies of the same document synchronized with each other in real-time is a complex challenge. This paper describes the differential synchronization algorithm. Differential synchronization offers scalability, fault-tolerance, and responsive collaborative editing across an unreliable network. 1 Conventional Strategies The three most common approaches to synchronization are ownership, event passing and three-way merges. These methods are conceptually simple, but all have drawbacks. link to googletalk video and mobWrite sw
