An efficient video watermarking approach using scene change detection
Jeebananda Panda, Prince Garg · 2016
In this paper, we have used a method based on DWT-SVD to insert and extract the watermark in an .avi file using a gray scale image as watermark through four different approaches. Performance comparison of all this four methods has been presented in this paper. To achieve low pay load with high robustness was the aim of this work. The 3rdand 4thmethod presented in this paper uses scene change detection technique for insertion of watermark as that particular frame of video having scene change characteristics is one of the most important frame in the video. The 4thmethod is found to be of lowest payload as compared to all other three methods and also results high robustness particular to frame swapping, frame dropping and mpeg compression. The performance of watermarking methods is calculated by peak signal to noise ratio and correlation coefficient to measure the robustness of the watermark schemes against different attacks.
