10th Mediterranean Electrotechnical Conference on Information Technology and Electrotechnology for the Mediterranean Countries
作者: Rejeb, B Anheier, W Univ Bremen Inst Electromagnet Theory & Microelect D-28334 Bremen Germany
Fractal image compression insures high compression ratio and image fidelity, however, it suffers from long encoding time. Real time fractal coding requires high throughput not achievable by software implementations or... 详细信息

Digital watermarking with complex wavelets
收藏 引用
作者: Loo, Patrick Kingsbury, Nick Signal Processing Group Dept. of Engineering University of Cambridge Cambridge CB2 1PZ United Kingdom
In this paper, we propose a watermarking algorithm in the complex wavelet domain. We then model watermarking as a communication process and show that the complex wavelet domain has relatively high capacity and is a po... 详细信息
