Conference on visual communications and image processing 2004
作者: Vila-Forcen, JE Koval, O Voloshynovskiy, S Univ Geneva Dept Comp Sci CH-1211 Geneva Switzerland
In the paper we advocate image compression technique in the scope of distributed source coding framework. The novelty of the proposed approach is twofold: classical image compression is considered from the positions o... 详细信息

Conference on visual communications and image processing 2004
作者: Song, IW Kim, CS Lee, SU Seoul Natl Univ Signal Proc Lab Sch Elect Engn & Comp Sci Seoul South Korea
In this paper, we develop a tree-structured predictive partial matching (PPM) scheme for progressive compression of PointTexture images. By incorporating PPM with tree-structured coding, the proposed algorithm can com... 详细信息

作者: Klompenhouwer, MA Velthoven, LJ Philips Res Labs NL-5656 AA Eindhoven Netherlands
Flat panel displays, such as liquid crystal displays (LCDs), typically emit light during the whole frame time. In contrast, traditional cathode ray tubes (CRTs) emit light as very short pulses, which gives the CRT a b... 详细信息
