In image watermarking, information is embedded into cover media to prove ownership.
Various watermarking techniques have been proposed by many authors in the last several …

In this article, a new projection neural network (PNN) for solving-minimization problem is
proposed, which is based on classic PNN and sliding mode control technique. Furthermore …

The field of digital watermarking has recently seen vast interests covering theoretical
studies, novel techniques, attacks and analysis. This is due to the fact that over the last 15 …

分析了一种小波域数字水印算法, 利用人类视觉模型对算法进行了改进. 选取一幅有实际意义的
二值图像作为水印, 在对原始图像进行多级小波分解后, 通过修改中频系数来进行水印嵌入 …

This paper proposes a wavelet watermarking scheme for video authentication. The discrete
wavelet transform (DWT) has been used extensively in recent years in watermarking …

The essential performance metrics of a robust watermark include robustness,
imperceptibility, watermark capacity and security. In addition, computational cost is important …

Self-assessment is a crucial component of learning. Creating effective questions is time-
consuming, however, because it may require considerable resources and the skill of critical …

In this paper, we propose a robust watermark technology that can be used to protect
copyright. We enhance robustness of the watermark such that it can be used to protect the …

The digital revolution has resulted in explosion of knowledge. It has encouraged and
motivated digitization of the intellectual artefact. This creates issues of piracy and copyright …

A robust cover content extraction and embedding technique that trades off between visual
quality and embedding capacity is proposed in this paper. In addition, adaptive quantization …
