Efficient Multilevel Reversible Data Hiding for Video Sequences Using Temporal and Spatial Approach

Year: 2009

Type: conference-paper

Abstract: Reversible data hiding can guarantee that the original image can be recovered from the marked image without any distortion. In this paper, an efficient multilevel reversible data hiding algorithm for video sequences is presented. Since the gray level distribution of the difference map is Laplacian, the peak point of the distribution thus leads into high data hiding capacity and good image quality. We also show that the peak signal to noise ratio (PSNR) lower bound of our proposed algorithm outperforms one by applying the previous best reversible data hiding algorithm the to each image frame in the video sequence directly. Based on four popular test video sequences, experimental results demonstrate the data hiding capacity and image quality advantages of our proposed data hiding algorithm.
