• 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 ...
  • Peak Transform for Efficient Image Representation and Coding 

    He, Zhihai, 1973- (IEEE, 2007-07)
    In this work, we introduce a nonlinear geometric transform, called peak transform (PT), for efficient image representation and coding. The proposed PT is able to convert high-frequency signals into low-frequency ones, ...
