Self-conjugate watermarking technique for halftone images
收藏 引用
ELECTRONICS LETTERS 2003年 第4期39卷 356-358页
作者: Fu, MS Au, OC Hong Kong Univ Sci & Technol Dept Elect & Elect Engn Hong Kong Peoples R China
A novel method for hiding visual patterns in a single error diffused halftone image is presented, called self-conjugate error diffusion (SCED). The hidden patterns appear on the halftone image when the halftone image ... 详细信息

46th IEEE International Midwest Symposium on Circuits and Systems
作者: Saponara, S Fanucci, L Terreni, P Univ Pisa Dept Informat Engn I-56122 Pisa Italy
The 3D Discrete Cosine Transform (DCT) extends the energy compaction properties of conventional 2D-DCT to integral 3D images and to the spatio-temporal coding of 2D video sequences. This paper addresses the problem of... 详细信息

image compression using wavelets and JPEG2000: a tutorial
收藏 引用
ELECTRONICS & COMMUNICATION ENGINEERING JOURNAL 2002年 第3期14卷 112-121页
作者: Lawson, S Zhu, J Univ Warwick Sch Engn Coventry CV4 7AL W Midlands England
The demand for higher and higher quality images transmitted quickly over the Internet has led to a strong need to develop better algorithms for the filtering and coding of such images. The introduction of the JPEG2000... 详细信息

video coding using greedy decompositions on generalised bit-planes
收藏 引用
ELECTRONICS LETTERS 2002年 第11期38卷 507-508页
作者: Caetano, R da Silva, EAB Ciancio, AG Univ Fed Rio de Janeiro PEE COPPE DELEE BR-21945970 Rio De Janeiro Brazil
A novel method for performing greedy decompositions using generalised bit-planes is proposed. It provides an elegant solution to the trade-off between quantisation of coefficients and number of passes in the matching ... 详细信息

Quantisation step selection schemes in JPEG2000
收藏 引用
ELECTRONICS LETTERS 2002年 第12期38卷 547-549页
作者: Long, M Tai, HM Yang, S Univ Tulsa Dept Elect Engn Tulsa OK 74104 USA
Modified quantisation step selection schemes for the uniform dead-zone scalar quantisation as used in Part I of the JPEG2000 standard are presented. Effects of these quantisation schemes on the lossy compression perfo... 详细信息

Improved searching scheme for fractal image coding
收藏 引用
ELECTRONICS LETTERS 2002年 第25期38卷 1653-1654页
作者: Lai, CM Lam, KM Siu, WC Hong Kong Polytech Univ Dept Elect & Informat Engn Ctr Multimedia Signal Proc Hong Kong Hong Kong Peoples R China
The authors propose using a non-symmetric window to search for the best matched domain block based on the local variances method. Experimental results show that the proposed scheme can achieve a speedup of 50% with on... 详细信息

Hausdorff distance for robust and adaptive template selection in visual target detection
收藏 引用
ELECTRONICS LETTERS 2002年 第25期38卷 1651-1653页
作者: Gastaldo, P Zunino, R Univ Genoa DIBE I-16145 Genoa Italy
Template selection is often crucial for target-detection methods;the Hausdorff distance enhances template matching by implicitly encoding the notion of resemblance. In addition, Hausdorff metrics can build up a decisi... 详细信息

Using inter-frame dependence history to select intra-refresh blocks
收藏 引用
ELECTRONICS LETTERS 2002年 第22期38卷 1337-1338页
作者: Zhao, C Ngan, KN Zhang, J Mathew, R Zhang, X Nanyang Technol Univ Sch Comp Engn Singapore 639798 Singapore Motorola Australia Res Ctr Botany NSW 2019 Australia
To prevent error propagation in predictive video coding, intra-refresh methods are often employed. Here, a new algorithm for macroblock intra-refresh that is based on pixel level inter-frame dependence history is prop... 详细信息
