一种改进的基于小波变换的数字水印算法

An improved digital watermarking algorithm based on DWT

本文根据小波变换原理和LSB技术提出了一种提高鲁棒性的灰度图像水印算法,使水印系统抗攻击能力大大增强。水印的提取并不需要原始载体图像的参与,实现了真正意义上的盲水印检测。

This article according to the wavelet transformation principle and the LSB technology proposed one kind ennanced the robust gradation picture watermark algorithm, caused the watermark system anti-attack capability big enhancement. The watermark withdraws certainly does not need the primitive carrier picture the participation, has realized in the true significance blind watermark examination.
