In this paper, a novel robust color image watermarking method based on Discrete Cosine
Transform (DCT) and Discrete Wavelet Transform (DWT) is proposed. In this method, RGB …

Color multi-watermarking is a challenge in the field of copyright protection, and the key in the
color multi-watermarking technology is how to determine the optimal embedding regions …

Abstract Polar harmonic Fourier moments (PHFMs) are very effective global image
descriptors and can be used in many areas of digital image processing. However, the …

Recently, the task of validating the authenticity of images and the localization of tampered
regions has been actively studied. In this paper, we go one step further by providing solid …

With the advent of technology, digital image watermarking turns to be an effective technique
to protect digital images from illegal usages and manipulation. In digital image …

In the process of network transmission, medical images are maliciously attacked to cause
the loss of diagnostic data or the leakage of patient privacy. To solve this problem, this paper …

In recent years, online video sharing platforms have been widely available on social
networks. To protect copyright and track the origins of these shared videos, some video …

Featured Application This work embeds the watermark images into host images, realizing
the robustness to common attacks and geometric attacks, which can be applied for copyright …

Watermarking by Zernike moments has been proven to be effective in providing high
rotational resistance. However, due to the high computational complexity, the conventional …

Geometric attacks such as rotation and scale can destroy the synchronization of
watermarking, designing a geometric-distortion resilient watermarking is currently a …
