fragile watermark

基本解釋

Semi-Fragile watermark has attracted attention due to its important role in content authentication for multimedia.
半脆弱水印因?yàn)樵诙嗝襟w內(nèi)容認(rèn)證方面的重要作用而受到人們密切的關(guān)注。
Meanwhile, besides telling you whether an image has been tampered, the fragile watermark can reflect the distortion status truly and intuitively.
同時(shí)，脆弱性水印不僅能判斷圖像的真實(shí)性，還能準(zhǔn)確、直觀地定位篡改信息。
In order to differentiate incidental attacks and malicious attacks, semi-fragile watermark must be robust against content-protection image processing.
為了能夠區(qū)分偶然攻擊與惡意篡改，半脆弱水印需要對(duì)一般的內(nèi)容保護(hù)圖像操作有一定的魯棒性。

脆弱水印
After all watermark pixel is embedded, get the image with fragile watermark.
當(dāng)全部水印像素嵌入完畢后,即得到含有脆弱水印的圖像。
易損水印
A fragile watermark algorithm for digital image based on the image content is proposed.
本文給出了一種基于圖像內(nèi)容的易損水印算法,該算法的水印生成和嵌入都在圖像本身中進(jìn)行。
易碎水印
Experiment results show that fragile watermark is sensitive to tampering.2.
實(shí)驗(yàn)表明該易碎水印對(duì)篡改是敏感的。
電子、通信與自動(dòng)控制技術(shù)
脆弱水印
Different form most former fragile watermark algorithm which embeds the watermark signal into the spatial localization, this approach embeds the watermark bit stream in the discrete wavelet domain of the image by quantifying the corresponding coefficients.
與以往大多數(shù)把水印信息隱藏在信號(hào)空域中的脆弱水印不同，本文采用適當(dāng)?shù)牧炕椒?，通過(guò)量化圖像離散小波變換后的小波系數(shù)，把水印信號(hào)嵌入圖像的離散小波域中。
