semi-fragile watermark

基本解釋

Semi-fragile watermark resisting to JPEG compression while maintaining high detection ability to tamper has been the emphasis in this area.
由於JPEG壓縮應(yīng)用的普遍性，在保持較高的對篡改檢測能力的情況下，提高抗JPEG壓縮性能一直是半脆弱水印的重要問題。
The multipurpose watermark is divided into two parts: robust watermark and semi-fragile watermark. The robust watermark is used to provide the copyright protection of image;
多功能水印被分爲(wèi)兩個(gè)部分，魯棒水印和半脆弱水印，其中魯棒水印實(shí)現(xiàn)內(nèi)容的版權(quán)保護(hù)；
Papers completed the watermark embedded in it after the attacks of the anti-testing, to determine how to tamper with the regional and tampering with the type of semi-fragile watermarking method.
論文在完成水印的嵌入之後對它的抗攻擊性進(jìn)行檢測，講述了如何確定篡改區(qū)域和篡改類型的半易損水印的方法。
