A REVIEW ON VIDEO WATERMARKING TECHNIQUES

Abstract

In this paper, systems utilized in video watermarking are examined with literature survey and after that the deficiency are investigated and as end proposition. Watermarking is a procedure of embedding the hidden information in interactive media framework in multimedia as picture, video, text for the identification and copyright. The fundamental goals of video watermarking are imperceptibility, robustness, and capacity of information. Several available methods for hiding data, Cryptography, spatial domain and steganography .The spatial area technique includes a calculation that specifically works on the pixel estimation of the host image. DCT transform and DWT transform are very common algorithms are used in video watermarking, PCA Based Video Watermarking Technique are also very useful technique. It mainly focuses on study of various techniques for video watermarking and finding deficiencies for improvement of quality metrics.
