In this paper a blind robust watermarking method based on hybrid ۳-D transform is proposed. The hybrid ۳-D transform is derivedby employing ۲-D Contourlet transform along with ۱-D wavelet transform. In the proposed method, each frame of video is split toodd and even columns and the ۳-D transform is applied to both of them. The signature is watermarked in the even part of the videoby using the high energy coefficients of the odd part. Experimental results indicate low degradation of quality of the watermarkedvideo, along with high robustness of the watermarked video against common attacks in comparison with other tested blind videowatermarking methods.
