zero-tree coding for Random Phase Hologram Compression  34
Zero-Tree Coding for Random Phase Hologram Compression

34th International Technical Conference on Circuits/Systems, Computers and Communications (ITC-CSCC)
作者: Kim, Jin-Kyum Seo, Young-Ho Kim, Dong-Wook Kwangwoon Univ Dept Elect Mat Engn Seoul 01897 South Korea
Holography has the potential to be the ultimate 3D experience. Since holography has a very high data amount compared with 2D image, a method for efficiently compressing it is needed. In this paper, we introduce a zero... 详细信息

COMPUTERS & MATHEMATICS WITH APPLICATIONS 2012年 第5期64卷 1140-1152页
作者: Wu, Bing-Fei Huang, Hao-Yu Chen, Yen-Lin Natl Taipei Univ Technol Dept Comp Sci & Informat Engn Taipei 10608 Taiwan Natl Chiao Tung Univ Dept Elect & Control Engn Hsinchu 30050 Taiwan
This paper proposes a block-edge-based Single-Pass Perceptual Embedded zero-tree coding (SPPEZC) method. SPPEZC combines two novel compression concepts, called Block-Edge Detection (BED) and the Low-Complexity and Low... 详细信息

Conference on Storage and Retrieval for Image and Video Databases V
作者: NguyenPhi, K Weinrichter, H Technische Univ. Wien (Austria)
We propose anew simple image coder based on Discrete Wavelet Transform (DWT). The DWT coefficients are coded in bitplanes. We use a variable order Markovian model to code the DWT coefficient bitplanes. Recently, we ha... 详细信息

Conference on Human Vision & Electronic Imaging
作者: Geisler, WS Perry, JS Univ Texas Ctr Vis & Image Sci Austin TX 78712 USA
Foveated imaging exploits the fact that the spatial resolution of the human visual system decreases dramatically away from the point of gaze. Because of this fact, large bandwidth savings are obtained by matching the ... 详细信息

2012 International Conference on Image,Vision and Computing(ICIVC 2012)
作者: Lv Shu Ping Guo Yang College of Automation Harbin Engineering University
According to the high and low frequency distribution characteristics of wavelet coefficients that were given by Wavelet transform decomposition of images, in this paper, a improved algorithm was proposed for the disad... 详细信息

Huazhong Ligong Daxue Xuebao/Journal Huazhong (Central China) University of Science and Technology 2001年 第9期29卷 95-98页
作者: Keita, A. Peng, J. Inst. For Pattern Recognition and AI HUST Wuhan 430074 China
It shows that prior information on the location where quantized value of large coefficients is comparative to that of coefficients is available in coding when natural images are decomposed on wavelet bases. The high e... 详细信息
