基于Contourlet变换的双重视频水印方案
Dual Video Watermark Scheme Based on Contourlet Transform
摘要
Abstract
A dual video watermark scheme based on Contourlet transform is proposed.Performed Contourlet transform on Ⅰ-frame in MPEG system, and srambled and encrypted watermark using hyperchaos sequence generated by simple two-dimentional hyperchaos system.Low frequency coefficients embedded destructive watermark to lose the video's value and high frequency coefficients embedded robust watermark to protect copyright.Experimental results show that only authorized users can get high-fidelity video information and the algorithm provides a new way for video copyright protection.关键词
