Zero-watermarking of light field images using fractional-order radial harmonic fourier moments and chaotic logistic-may map

Alexandria Engineering Journal
Unlike traditional images, light field images capture comprehensive scene information, enabling novel post-capture manipulations. However, this very richness makes them vulnerable to tampering.

MultiMark: Multi-Isosurface Embedded Watermarking for Signed-Distance Fields

Mathematics
Signed-Distance Fields are widely used in high-value applications owing to their continuity and topological flexibility, yet they remain highly vulnerable to replication and tampering. Existing watermarking techniques for these fields directly modify the

Attack on watermarking system by the combination of the total variation and wavelet decomposition

Tạp chí Khoa học Đại học Mở Thành phố Hồ Chí Minh - Kỹ thuật và Công nghệ, 2011
In 1990, Tanaka has been publishing a first paper [8] to describe a method for hiding a message in a picture. This work marked the beginning a new branch of computer science. It’s watermarking. Nowadays, we have an exact definition of watermarking is the
