A Digital Video Watermarking Algorithm Based on LSB and DCT

摘要

In this paper a new watermarking algorithm is proposed for videos. The developed method embeds a binary image as watermark into a colour avi video..In the proposed method, LSB and DCT both are embedded in the video frames. We compare our algorithm with 2-LSB using Peak signal-to-noise ratio (PSNR). Experimental results show that the quality of the watermarked image is higher. PSNR value is 63.74db in proposed method. This is higher compare to the other method.
