A lagrangian optimized rate control algorithm for the H.264/AVC encoder
The H.264/AVC video coding standard has been recently proposed by the Joint Video Team of ITU-T and MPEG experts. The AVC encoder achieves video bitstreams at the same quality as ...

Variable block-size transform and entropy coding at the enhancement layer of FGS
This paper proposes the variable block-size transform and context-based entropy coding techniques for the enhancement layer of FGS (Fine Granularity Scalable) video coding. First,...

Low-complexity macroblock mode selection for H.264/AVC encoders
Lagrangian minimization is one of the most powerful tools for Rate-Distortion optimal coding mode selection. However, in the latest video compression standard H.264/AVC, the total...

Audio-visual speaker identification using coupled hidden Markov models
In this paper, we investigate the use of the coupled hidden Markov models (CHMM) for the task of audio-visual text dependent speaker identification. Our system determines the iden...

Rate-distortion optimized video streaming with multiple deadlines
We extend a recently-proposed framework for the rate-distortion optimized transmission of packetized media. The original framework assumed that media packets each have a single arr...
