Abstract: |
A blind detection video watermarking algorithm in complex wavelet transform (CWT) domain is proposed here. The host video sequence is firstly partitioned into several video shots. Then each shot is projected onto 3-D CWT domain. In order to achieve robustness while keeping imperceptible, a perceptual mask which is derived from 3-D complex wavelet coefficients is introduced to weight the watermarks and the results is added back to the complex wavelet coefficients. Finally, the 3-D inverse CWT (ICWT) is applied to obtain the watermarked video shots. Experimental results illustrate that the proposed algorithm is superior to the algorithm in discrete wavelet transform (DWT) domain. |
