On object-based compression for a class of dynamic image-based representations
An object-based compression scheme for a class of dynamic image-based representations called "plenoptic videos" (PVs) is studied in this paper. PVs are simplified dynami...

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...

MPEG-4 video object-based rate allocation with variable temporal rates
This paper describes a bit allocation algorithm that can achieve a constant bit rate when coding multiple video objects (MVO's), while improving the rate-distortion (R-D) per...
