Activity Analysis, Summarization, and Visualization for Indoor Human Activity Monitoring
(IEEE, 2008-11)In this work, we study how continuous video monitoring and intelligent video processing can be used in eldercare to assist the independent living of elders and to improve the efficiency of eldercare practice. More ... -
Joint Source Channel Rate-Distortion Analysis for Adaptive Mode Selection and Rate Control in Wireless Video Coding
(IEEE, 2002-06)In this paper, we first develop a rate-distortion (R-D) model for DCT-based video coding incorporating the macroblock (MB) intra refreshing rate. For any given bit rate and intra refreshing rate, this model is capable of ... -
Lowpass Filtering of Rate-Distortion Functions for Quality Smoothing in Real-Time Video Communication
(IEEE, 2005)In variable-bit-rate (VBR) video coding, the video is pre-processed to collect sequence-level statistics, which are used for global bit allocation in the actual encoding stage to obtain a smoothed video presentation ... -
Power-Rate-Distortion Analysis for Wireless Video Communication under Energy Constraints
(IEEE, 2004)Mobile devices performing video coding and streaming over wireless and pervasive communication networks are limited in energy supply. To prolong the operational lifetime of these devices, an embedded video encoding system ...
