Reliable detection of video watermarks using inferential statistics
Errors in watermark detection can cause serious problems, such as erroneous copy control and misindication of illegal copying. This paper proposes a new watermark method which prevents detection errors by using the expectation-maximization algorithm from inferential statistics. Experimental evaluations have confirmed its reliability.
