A blind watermarking algorithm based on image integer wavelet transform 基于圖像整數(shù)小波變換的盲數(shù)字水印嵌入算法
( 3 ) presenting digital watermarking embedding algorithm based on quantization in low - frequency in dwt domain ( 3 )提出了基于量化音頻小波域低頻系數(shù)的水印嵌入算法。
According to zero - watermarking , a zero - embedding algorithm for multiple watermarks was proposed based on wavelet and chaos 摘要根據(jù)零水印概念,提出一種基于小波和混沌的多重水印零嵌入算法。
Aiming at a specific binary images - pdf417 2d barcode , a new information hiding method based on boundary shift was brought up 針對(duì)一類特定的二值圖形pdf417二維圖形碼,提出了基于邊界移位的隱藏信息嵌入算法。
At the same time , the direction along which the watermark bit is embedded is also adaptive to the local geometry , which is rather a novel idea 同時(shí),與已往自適應(yīng)水印嵌入算法不同的是:水印嵌入方向也自適應(yīng)于局部幾何特征。
