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

Unlike traditional images, light field images capture comprehensive scene information, enabling novel post-capture manipulations. However, this very richness makes them vulnerable to tampering. This paper proposes lossless copyright protection of light-field images based on a robust zero-watermarkin...
