Resource Allocation and Performance Analysis of Wireless Video Sensors
(IEEE, 2006-05)Wireless video sensor networks (WVSNs) have been envisioned for a wide range of important applications, including battlefield intelligence, security monitoring, emergency response, and environmental tracking. Compared to ... -
Energy-Aware Portable Video Communication System Design for Wildlife Activity Monitoring
(IEEE, 2008)In this paper, we introduce our recent research and development effort on energy-efficient portable video communication system design for wildlife activity monitoring. The capability of seeing what an animal sees in the ... -
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 ... -
Adaptive Critic Design for Energy Minimization of Portable Video Communication Devices
(IEEE, 2008-08)Portable video communication devices operate on batteries with limited energy supply. However, video compression is computationally intensive and energy-demanding. Therefore, one of the central challenging issues in ... -
Fine-Granularity Transmission Distortion Modeling for Video Packet Scheduling Over Mesh Networks
(IEEE, 2010-01)Packet scheduling is a critical component in multi-session video streaming over mesh networks. Different video packets have different levels of contribution to the overall video presentation quality at the receiver side. ... -
Reliability Analysis for Global Motion Estimation
(IEEE, 2009-11)Global motion estimation (GME) is the enabling step for many important video exploitation tasks. In this work, we focus on indirect GME methods which have low computational complexity. Typically, an indirect GME method ... -
Subgraphs Matching-Based Side Information Generation for Distributed Multiview Video Coding
(EURASIP Journal on Advances in Signal Processing, 2009)We adopt constrained relaxation for distributed multiview video coding (DMVC). The novel framework integrates the graphbased segmentation and matching to generate interview correlated side information without knowing the ... -
Lossless Image Compression Using Super-Spatial Structure Prediction
(IEEE, 2010-04)We recognize that the key challenge in image compression is to efficiently represent and encode high-frequency image structure components, such as edges, patterns, and textures. In this work, we develop an efficient ... -
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 ... -
Real-time Tracking and Pose Estimation for Industrial Objects using Geometric Features
(IEEE, 2003-09)This paper presents a fast tracking algorithm capable of estimating the complete pose (6DOF) of an industrial object by using its circular-shape features. Since the algorithm is part of a real-time visual servoing ... -
Calculating the 3D-Pose of Rigid-Objects Using Active Appearance Models
(IEEE, 2004-05)This paper presents two different algorithms for object tracking and pose estimation. Both methods are based on an appearance model technique called Active Appearance Model (AAM). The key idea of the first method is to ... -
Analysis of Clipping Effect in Color Images Captured by CCD Cameras
(IEEE, 2004-10)Camera sensors (CCD) have a limited dynamic range that constrains the brightness of the incident light that can be quantified. In other words, if the ray of incident light is too intense, the sensor saturates and the ... -
