IEEE Custom Integrated Circuits Conference
作者: Miles, L Gambles, J Maki, G Ryan, W Whitaker, S Univ Idaho Ctr Adv Microelect & Biomol Res Post Falls ID 83854 USA
Low-density parity-check codes achieve coding performance which approaches the Shannon limit. Based on a novel method for deriving regular quasi-cyclic sub-codes, a radiation tolerant encoder was implemented in 0.25 m... 详细信息

Conference on Applications of Digital Image Processing XX
作者: Algazi, VR Avadhanam, N Estes, RR Univ. of California/Davis (United States)
Pre-processing images prior to encoding can remove noise, or unimportant detail, and thus improve the overall performance of the coder. Typical objective image quality metrics are obtained by computing a single or sev... 详细信息

IEEE Information Theory Workshop
作者: Cheng, S Xiong, ZX Texas A&M Univ Dept Elect Engn College Stn TX 77843 USA
We consider Slepian-Wolf code design (or source coding with side information) based on LDPC codes. We show that density evolution defined in conventional channel coding can be used in analyzing the Slepian-Wolf coding... 详细信息

IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM)
作者: Hong, Soongi Chung, Dahjung Choe, Yoonsik Yonsei Univ Sch Elect & Elect Engn Image Informat Lab Seoul 120749 South Korea
Although IBDI, a coding tool that increases internal bit depth to improve compression performance for high quality video, is able to significantly improve the coding efficiency, the internal memory increment problem o... 详细信息

The 2010 2nd International Conference on Future Computer and Communication(第二届未来计算机与通信国际会议 ICFCC 2010)
作者: Baoguo Du Hong Shen School of Computer Science and Technology University of Science and Technology of China China School of Computer Science and Technology University of Science and Technology of China China Scho
Distributed Video coding (DVC) is a new video coding which shifts the complexity from the encoder to the decoder. In DVC, the side information is only known at the decoder to exploit the source statistics. Therefore i... 详细信息

Disparity estimation with hierarchical block correlation for stereoscopic image coding
收藏 引用
Systems and Computers in Japan 1998年 第6期28卷
作者: Wentao Zheng Yoshiaki Shishikui Yutaka Tanaka Ichiro Yuyama NHK Science and Technical Research Laboratories Tokyo Japan 157
Disparity compensation is widely used to remove the spatial redundancies in stereoscopic image coding. In this paper, we present a disparity estimation algorithm called hierarchical block correlation, which is a hybri... 详细信息
