Drift-Compensated Robust Watermarking Algorithm for H.265/HEVC Video Stream

Abstract

It has been observed in the recent literature that the drift error due to watermarking degrades the visual quality of the embedded video. The existing drift error handling strategies for recent video standards such as H.264 may not be directly applicable for upcoming high-definition video standards (such as High Efficiency Video Coding (HEVC)) due to different compression architecture. In this article, a compressed domain watermarking scheme is proposed for H.265/HEVC bit stream that can handle drift error propagation both for intra- and interprediction process. Additionally, the proposed scheme shows adequate robustness against recompression attack as well as common image processing attacks while maintaining decent visual quality. A comprehensive set of experiments has been carried out to justify the efficacy of the proposed scheme over the existing literature.
