A performance analysis of objective video quality metrics for digital video watermarking

Rapid growth in sharing information using internet technologies laid the threats of copyright protection for digital multimedia contents. One of the remedy for intellectual property protection is Watermarking. This paper deals with numerous available digital video watermarking techniques and raised the issue of quality and size of watermarked video. Through experimental study, it has been shown that available quality metrics like, Peak signal to noise ratio (PSNR) and Structural similarity index (SSIM) are incapable to deal efficiently to analyze the quality degradation but out of two it has been claimed that SSIM results are more accurate as it is closer to the results obtained during subjective quality analysis. Further, using available video watermarking tools, variation in size of video has been analyzed.
