This paper presents a new blind and robust image watermarking scheme based on discrete
wavelet transform (DWT) and discrete cosine transform (DCT). Two DCT-transformed sub …

In highly open systems like the Internet, attribute-based access control (ABAC) has proven
its appropriateness. The specification and maintenance of ABAC policies however has …

Traditional statistical detectors of the discrete wavelet transform (DWT)-based image
watermarking use probability density functions (PDFs) that show inadequate matching with …

In this study, the concept of fractional wavelet packet transform is explored with its
application in digital watermarking. The core idea of the proposed watermarking scheme is …

Digital image watermarking is used to protect the copyright of digital images. In this study, a
novel blind logo image watermarking technique for RGB images is proposed. The proposed …

提出了一种基于多小波变换和分块SVD 的非盲水印算法. 选择彩色图像的饱和度分量作为水印
的嵌入域, 水印为有意义的灰度图像, 水印经Arnold 置乱后被嵌入到饱和度分量多小波变换的 …

Rapid growth in sharing information using internet technologies laid the threats of copyright
protection for digital multimedia contents. One of the remedy for intellectual property …

The purpose of this paper is to improve the robustness of traditional image watermarking
based on singular value decomposition (SVD) by using optimization-based quantization on …

Wavelet/frame shrinkage and nonlinear diffusion filtering are two popular methods for signal
and image denoising. The relationship between these two methods has been studied …

Explicit and recursive formulations are derived for the computation of refinable interpolatory
Hermite vector splines, of arbitrary odd degree, and supported on [− 1, 1], as well as for the …
