Review of Video Watermarking Techniques
IJIRST-International Journal for Innovative Research in Science & Technology|
There has been a remarkable raise in the data exchange over web and the general use of digital media. The interest with reference to digital watermarking right through the last decade is certainly due to the increase in the need of copyright protection of digital data. Applications of video watermarking in copy control, broadcast monitoring, video authentication, fingerprinting, copyright protection etc is immensely rising. The major aspects of information hiding are security, capacity and
... , capacity and robustness. Capacity deals with the amount of information that can be concealed. The ability of anyone detecting the information is robustness and refers to the resistance to modification of the cover content before concealed information is destroyed. Video watermarking algorithms normally prefers robustness. In a robust algorithm it is not possible to eliminate the watermark without precise degradation of the cover content. In this paper, features required to design a robust watermarked video for a valuable application. We review several algorithms, and introduce commonly used key technique. Aspire of this paper is to focus on the various domains of video watermarking techniques. The best part of the reviewed methods based on video watermarking highlight on the concept of robustness of the algorithm. Video Watermarking is a young and rapidly rising field in the area of multimedia. The aim of this paper is to focus on the various domains of video Watermarking techniques.
