In this paper, we investigate the benefits of a flexible, application-specific instruction set by adding a run-time Reconfigurable Functional Unit (RFU) to a VLIW processor. Preli...

The three-dimensional (3-D) SPIHT coder is a scalable or embedded coder that has proved its efficiency and its real-time capability in compression of video. A forward-error-correc...
Currently 3D animation rendering and video compression are completely independent processes even if rendered frames are streamed on-the-fly within a client-server platform. In suc...
We extend previous work on texture mapping video streams into virtual environments by introducing awareness driven video QoS. This uses movements within a shared virtual world to ...

We present a novel client-driven multi-view video streaming system that allows a user watch 3-D video interactively with significantly reduced bandwidth requirements by transmitti...
We describe a steganographic system which embeds secret messages into a video stream. We examine the signal path which typically includes discrete cosine transformation (DCT) based...

This paper presents a technique for the efficient compression of high dynamic range video (HDR) sequences. Such video sequences usually represent several orders of magnitude of r...
We present an efficient implementation of a state of the art algorithm PixelMatch for matching all pixels within consecutive video frames. The method is of practical interest for ...
