Real-time watermark embedding for high resolution video watermarking

Abstract

This paper addresses implementation issues for real-time watermark embedding scheme of High Definition(HD) resolution videos on personal computers. In most watermark applications, an embedding procedure should be built at low costs and at the same time the embedded watermarks should have robustness against signal and image processing as well as malicious attacks. This paper provides some performance optimization guidelines and a simplified Human Visual System (HVS) method for fast and robust watermark embedding. This work demonstrates a real-time watermark embedding process including HD MPEG-2 video decoding, watermark embedding and displaying on Intel architecture personal computers. Experimental results show optimized embedding performances and robustness against several malicious attacks commonly happened to videos.
