• Lossless Image Compression Using Super-Spatial Structure Prediction 

    Zhao, Xiwen Owen; He, Zhihai, 1973- (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 ...
  • 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 ...
