An Algorithm for Lossless Smoothing of MPEG Video
Interframe compression techniques, such as those used in MPEG video, give rise to a coded bit stream where picture sizes di er by a factor of 10 or more. As a result, bu ering is ...

A temporal error concealment method for MPEG coded video using a multi-frame boundary matching algorithm
Compressed video sequences are very sensitive to channel disturbances when they are transmitted through an unreliable environment such as a wireless channel. The transmission erro...

Data rate smoothing in interactive walkthrough applications using 2D prefetching
Compared to a geometric approach, image based rendering applied to 3D view reconstruction doesn't require 3D model construction and doesn't depend on the complexity of t...

Fast and automatic video object segmentation and tracking for content-based applications
The new video-coding standard MPEG-4 enables content-based functionality, as well as high coding efficiency, by taking into account shape information of moving objects. A novel alg...

Optimizing Algorithms for Region-of-Interest Video Compression, with Application to Mobile Telehealth
Wireless communication of video poses constraints on information capacity. Region-of-Interest (ROI) video coding provides higher quality in the ROI, but poorer quality in the back...
