Abstract
Theoretical modeling of watermarks allow prediction of the detector reliability and facilitates the development of more reliable systems. In particular, mathematical evaluation is relevant to estimate the rate at which “false alarms” occur. In this paper, the probability of incorrect detection (missed detection or false alarm) is expressed in terms of the watermark-energy-to-image-luminance-variance ratio. We present some counterintuitive results which show for instance that the reliability of detection significantly depends on spatial correlation in watermark. Moreover we find that a small but uncompensated random DC component in the watermark can have a significant effect on the reliability.
