This paper proposes a novel self-adaptation differential energy watermarking based on the Watson visual model, which inserts robust watermark into video
streaming according to the differential energy theory. This algorithm can control the watermark's embedding intensityof sub-low AC coefficients in the video streaming adaptivelybased on the Watson visual model. And it also can be self-adaptive cheesed that the region should be embedwatermarks according to the relationship between the
energy adjustable threshold and their differential energy.So watermark not only meets the non-visual perception, but also has the better robustness. Experiments show that thisalgorithm has strong robustness and security against theusual video attacks such as noise, filter and compressionattack etc with low complexity of energy computation andhigh capacity.Index Terms—sel

Abstract;Digital video data distribution through the Internet is becoming more common, and is now seen as apowerful marketing media by the entertainment
industry. These materials need to be protected to avoid copyright infringement issues. However, theyare encoded at a low bit-rate to facilitate Internet distribution and this poses a challenge to the watermarking operation. In this paper we present anextension to the Differential Energy Watermarking(DEW) algorithm, to use it in low bit-rateenvironment. We present the extension scheme andevaluate its performance in terms of watermarkcapacity, robustness and visual impact.

thank you so much Maddali V S Murali Krishna for your answer. in,fact I want to know practical tutorial or book or website that explain to me. how to implement DEW practically with video (step by step) even in c programming language, c++ or c#
please if you or anyone can help me
