| Abstract: | To dealing with the weak point of current algorithm which combines the wavelet transform and singular value decomposition, a new and improved digital video watermarking algorithm is offered： binary image as a watermark to the mixed-integer wavelet transform and singular value decomposition of the blind video watermarking extraction algorithm. We focus on the singular value decomposition of the video watermark embedding and detection, and security test; experiments show that the new proposed algorithm has higher transparency and better robustness on anti-attack than else. |
| Keywords: | video watermark integer wavelet transform singular value decomposition security test |
