DWT_shuiyin
- 提出了一个新的基于量化抖动和模式分组编码的盲数字图像水印算法,该算法首先在DWT(离散小波变换)的第 二层中频子带中随机选取相应位置的绝对值最大的系数作为水印的嵌入区间,对小波系数进行量化并根据分组编码原 理生成预嵌入模式,然后将一个二值水印图像嵌入到模式当中。-Proposed a new model based on quantitative jitter and packet-coded blind digital image watermarking algorithm, the

SVD_DWTimage
- 提出了一种新的基于离散小波变换(DWT)与奇异值分解(SVD)相结合的数字图像水印算法。该算法将原始图像作小波分解并将小波分解得到的低频子带进行分块，对每一块进行奇异值分解后，选取每块中最大的奇异值通过量化的方法嵌入经过Arnold置乱后水印信息。-A new wavelet transform based on discrete (DWT) and Singular Value Decomposition (SVD) combination of digital image watermark
