A Framework for Estimating the Capacity of Multi Channel Digital Image Watermarking

Abstract

Watermarking channel capacity is defined as the number of bits that can be embedded in an image with an arbitrarily low probability of detection error under a given distortion constraint. In recent literature, multi-channel watermarking channel capacity is defined as a function of the maximum amount of distortions introduced by the hider and attacker. In this paper, we provide a framework for estimating the capacity of multi channel digital image watermarking in practical setting by simulating two types of attacks.
