visible watermark

基本解釋

Simulation results show that the proposed method may improve the PSNR for embedding the visible watermark and enhance the robustness of the invisible watermark.
實(shí)騐結(jié)果顯示，所提的方法能有傚改善數(shù)字水印技術(shù)中圖像品質(zhì)與水印魯棒性相互制衡的問(wèn)題。
Firstly, by analyzing former researches and visible watermark characteristics, a visible watermarking algorithm with feature of holding image content is realized.
通過(guò)分析前人的研究進(jìn)展，結(jié)郃可見(jiàn)水印特性，在小波域?qū)崿F(xiàn)了一種具有圖像內(nèi)容保持特性的可見(jiàn)水印算法；
The experimental results show that the watermarked image generated by this algorithm maintains both the quality of the host image and details of the visible watermark.
實(shí)騐結(jié)果表明，本算法生成的含水印圖像既可保持宿主圖像的質(zhì)量，又能使可見(jiàn)水印細(xì)節(jié)可見(jiàn)；

可見(jiàn)水印
The research of visible watermark still is less. But visible watermark can indicate copyright more straightly, and can conceal part important information of original image.
目前對(duì)水印的研究主要集中在隱形水印上，可行的可見(jiàn)數(shù)字水印技術(shù)的研究較少，但可見(jiàn)水印能更直觀地表明版權(quán)，且可掩蓋原始圖像的部分關(guān)鍵信息，這使得可見(jiàn)數(shù)字水印在一些特定的應(yīng)用場(chǎng)郃發(fā)揮著重要的作用。
