Abstract :
This paper presents a video watermarking technique able to resist geometric attacks. The proposed method performs imperceptible watermarking of video in the spatio-temporal domain. Before embedding or detecting the watermark in the video, the location of the most appropriate triangles used for positioning the watermark must be found. For this reason, the interest points in each frame are first found using a spatio-temporal interest point detection method, and then the Delaunay triangulation is performed. Experimental evaluation demonstrates that the proposed scheme is able to withstand variety of attacks including common geometric attacks.
