That scheme involves altering the second and third elements drawn from the first left singular vector in the SVD [39]. Zhang et al. presented a robust watermarking scheme in which a binary bit is embedded within the largest singular value of each image block [40]. Note that the above ...

SVD-based digital image watermarking scheme In the past couple of years, several digital watermarking schemes have been proposed and based on DCT, DFT, and DWT transformations. In this paper, a singu... CC Chang,P Tsai,CC Lin - 《Pattern Recognition Letters》 被引量: 282发表: 2013年 A ...
Zero-watermarking has become a special way to address some issues about copyright protection in recent years since it was proposed by Wen, as it has the advantage of not making any modification to the original digital file [9]. Wang et al. proposed multiple zero-watermarking scheme based on ...
Compared with earlier schemes based on SVD, the proposed scheme has satisfying imperceptibility and improved payload. 展开▼ 机译:在本文中,我们提出了一种新颖的盲音频水印算法,该算法将奇异值分解(SVD)与离散小波变换(DWT)相结合。在我们的算法中,我们首先将重新排列的音频信号划分为多个块,然后在对...

This paper presents a blind, adaptive quantization index modulation (QIM)- and singular value decomposition (SVD)-based watermarking scheme to embed watermark bits in the approximation subband of the wavelet domain. The QIM technique adaptively determines the quantization step for each embedding block ...
The copy of the watermark is embedded into four sub-band coefficients which are very difficult to remove or destroy. The combination of DWT and SVD increases the security, robustness and imperceptibility of the scheme.Sapthagiri.KVishwanath Reddy.GGanga Bhavani...
