Automatic recovery of invisible image watermarks from geometrically distorted images
收藏 引用
JOURNAL OF ELECTRONIC IMAGING 2000年 第4期9卷 477-483页
作者: Braudaway, GW Mintzer, F IBM Corp Thomas J Watson Res Ctr Yorktown Heights NY 10598 USA
One method of attacking an imbedded invisible watermark is to create a derivative image that is geometrically distorted relative to the original. One attack, developed at Cambridge University, is called "StirMark... 详细信息

Spline-regularized ordered subsets expectation-maximization algorithms for emission computed tomography
收藏 引用
JOURNAL OF ELECTRONIC IMAGING 2003年 第1期12卷 17-24页
作者: Lee, SJ Paichai Univ Dept Elect Engn Taejon 302735 South Korea
We describe ordered subsets (OS) algorithms applied to regularized expectation-maximization (EM) algorithms for emission tomography. Our reconstruction algorithms are based on a maximum a posteriori approach, which al... 详细信息

Continuity of gamut mapping algorithms
收藏 引用
JOURNAL OF ELECTRONIC IMAGING 2006年 第1期15卷 013004.1-013004.1页
作者: Zolliker, Peter Simon, Klaus EMPA Swiss Fed Labs Mat Testing & Res Lab Media Technol CH-8600 Dubendorf Switzerland
The design of a gamut mapping algorithm (GMA) is always a compromise between preserving different competing aspects such as color, contrast, and lightness. A natural requirement of a GMA is that the algorithmic treatm... 详细信息
