A Robust Video Watermarking Approach based on a hybrid SVD/DWT Technique
Abstract— A comparative analysis to determine the most effective video watermarking algorithm between SVD/DWT hybrid and Singular Value Decomposition (SVD) is reported in this paper. Blind video watermarking schemes are simulated and attempts made to recover the watermark after some signal processing attacks such as median filtering and Histogram equalization. The quality of the extracted watermark was then measured using the SSIM index.
From the computer simulation results using a diverse set of standard video clips the SVD/DWT hybrid performed better than the reference. An average value of the SSIM index of 0.98 was obtained. The SVD transform values varied from 0.57 to 0.78 for histogram equalization attacks and 0.83 to 0.9 for median filtering attacks. The results reveal the superiority of the SVD/DWT hybrid technique over SVD for digital rights enforcement.
