Transparency and robustness are two conflicting requirements demanded by digital image
watermarking for copyright protection and many other purposes. A feasible way to …

Watermarking is the process of embedding information in a carrier in order to protect the
ownership of text, music, video and images, while steganography is the art of hiding …

This paper presents a novel noise-robust scheme for watermark embedding and extraction,
applicable on the broad scientific field of information security, including digital encryption for …

Digital watermarking remains the rapidly developed branch of the computer science due to
the huge amount of internet resources, requiring a defense. In the past decades, many …

This paper describes a newly-created image database termed as the NITS-IQA database for
image quality assessment (IQA). In spite of recently developed IQA databases, which …

In this paper, a new watermarking scheme based on Human Visual System (HVS) modeling
is proposed. The approach consists in building computational models which take into …

This paper presents a novel method for open-loop watermarking of H. 264/AVC bitstreams.
Existing watermarking algorithms designed for previous encoders, such as MPEG-2 cannot …

This article details the conception, design, development and analysis of invisible, blind and
robust color image watermarking algorithms based on the wavelet transform. Using error …

In this paper, a new no-reference image quality metric is proposed to estimate the quality of
watermarked images automatically based on combining objective metrics using neural …

This work is motivated by the limitations of statistical quality metrics to assess the quality of
images distorted in distinct frequency ranges. Common quality metrics, which basically have …
