Abstract :
We propose a blind image watermarking algorithm that has three main features: (1) it satisfies an undetectability constraint with respect to a statistical image model, (2) it rejects host-signal interference and (3) it is robust against additive and multiplicative noise, filtering, cropping, and random bending.
