• Adaptive Critic Design for Energy Minimization of Portable Video Communication Devices 

    Sun, Zhao; Chen, Xi; He, Zhihai, 1973- (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 ...
  • Reliability Analysis for Global Motion Estimation 

    Chung, Yu-Chia, 1979-; He, Zhihai, 1973- (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 ...
  • Resource Allocation and Performance Analysis of Wireless Video Sensors 

    He, Zhihai, 1973-; Wu, Dapeng (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 ...
