DCT-DWT-SVD数字水印技术结合了离散余弦变换(DCT)、离散小波变换(DWT)和奇异值分解(SVD),用于保护数字内容的版权和完整性。首先,使用DCT和DWT对原始图像进行变换,以提取出其频域和空域的特征。接着,利用SVD将水印信息嵌入到变换后的图像中,通过调整图像的奇异值来隐藏水印信息。在提取水印时,对含水印图像再次进行...

This paper proposes a DWT-DCT-SVD and LWT-DCT-SVD based image watermarking technology, as well as a comparison of the DWT and LWT systems. The host picture is first divided into sub-bands throughout the embedding phase using multilevel DWT or LWT. The image is divided into various high ...
Image watermarking is the vital process in leveraging digital rights management for valuable intellectual properties. Recently, large number of works was f
This paper proposed a blind video watermarking algorithm based on DWT , DCT and SVD.The key frames were selected quickly by color difference of red and green channel in video frames , then performed the blue component of each of key
