A robust watermarking scheme for region of interest in H.264 scalable video coding

In this paper, we propose a scheme to protect the region of interest (ROI) in the scalable video coding (SVC) with watermark. By embedding watermarks only in ROI, the most important contents of video are protected and less important areas are not touched, so the video protection is more efficient with less computing cost. In our scheme, ROIs in the video are detected and extracted automatically. Different watermarks can be offered for different ROIs in different layers of video. Meanwhile, watermarks can be extracted without referential video. Experiments were performaned by using the joint scalable video model (JSVM) 9.18. Experimental results show that the proposed scheme can protect ROI efficiently and the watermarks are robust against some common attacks.
