The security of digital contents, therefore, constitutes a quintessential aspect of copyright protection in today's multimedia related industries. For this very reason, the integrity, verification and authentication of digital videos form an active research area today .
Digital watermarking of HEVC encoded videos may be a difficult task, because the codec eliminates most of the redundancy that the watermarking process may exploit. Casual embedding of a watermark, thus, may escalate the final video file size or otherwise affect the quality of the video; a carefully conceived embedding strategy is thus needed.
Keeping these in view, we intend to propose an HEVC watermarking scheme that would have negligible effect on both the video quality and the final file size. Our strategy is to embed a watermark, during the encoding process, that can be completely extractable during the decoding process.
Normally, a watermark may either be embedded in the spatial domain or the frequency domain. With spatial domain video watermarking, the hidden data may be lost during the quantization step of the underlying video codec.
One solution to this problem is to embed the watermark in such a way that it survives the quantization loss. But this may come at the cost of lower imperceptibility. A better solution is to go for the frequency domain and better embed the watermark after the quantization step, i.
In our approach, we adopt this later approach and embed the watermark message in the selected non-zero QTCs of all the frames of the video.
The rest of the paper is organized as follows. For a better comprehension of this article, the first part of Section outlines a brief overview of the state of the art HEVC standard. The second part of the same section provides a brief literature review regarding the watermarking techniques proposed for various video coding standards, in vogue. The proposed watermarking algorithm is outlined in Section 0. As illustrated in Fig. In other words, more than 16, points should be searched to find the best MV for current block.
In interprediction stage, asymmetric partition AMP partitioning and ME process can promote the matching precision. However, the coding time is increased significantly for the novel complex design. Therefore, this paper presents an efficient approach to reduce the calculation burden in interprediction. Firstly, we find out a fast decision method so that some prediction units are divided into asymmetric partitions directly without the complex calculation. And then, based on the motion degree function we defined, the motion search range of ME can be adaptively adjusted.
The remainder content of this article is organized as follows.
Our proposed method is described in Section 2. Section 3 demonstrates the experimental comparison between our proposed approach and other methods and discusses the coding performance of the proposed algorithm. Finally, we summarize this paper in Section 4.
The related previous work To reduce interprediction computational burden for HEVC encoder, many researchers have proposed various fast methods. These methods aim to simplify PU mode decision process that we sum up as follows.
A different CU visiting order is stated in Ref. A set of procedures for partition structure determination is designed in Ref. An early terminating fast intermode decision algorithm, namely hierarchical intermode decision HIMD , is presented in Ref. A course of low complexity mode decision algorithm consists of four early termination strategies and this approach uses co-located block depth information and current block size information to terminate RDO process [ 20 ]. A reverse CU access approach is proposed in Ref.
A fast CU partitioning algorithm is provided in Ref.
A fast interprediction mode decision algorithm is proposed in our previous work [ 23 ] that uses current block edge information to simplify RDO process so as to accelerate coding time for HEVC encoder.
Furthermore, complex ME process in HEVC encoder requires a huge calculation, so many low-complexity algorithms have been presented to make improvement on ME process. A block motion information derivation is described in Ref.
A fast algorithm is introduced in Ref. A fast ME decision method is provided in Ref.
