Recently, many data embedding schemes using the quantized DCT coefficients have been proposed for achieving the robustness. However, most of the schemes lack to strike a trade off between the embedding capacity and the visual quality. Achieving more embedding capacity by maintaining the visual quality has become a challenging task. Most of the DCT based data embedding schemes result in various visual distortions for not considering the HVS characteristics while embedding. The widely used visual…

A reversible data embedding scheme for MPEG-4 video using HVS characteristics
TLDR
A reversible data embedding scheme for MPEG-4 video which embed the data into middle frequency coefficients of quantized DCT blocks and use HVS based visual quality metrics is proposed.
Reversible Data Hiding Scheme for the H.264/AVC Codec
TLDR
This paper investigates the possibility to introduce the DCT based reversible data hiding method, proposed initially for compressed images, to H.264/AVC codec and shows that exploiting the P frames improves considerably the video quality and the embedding capacity.

TLDR
A reversible data embedding scheme for MPEG-4 video, striking the trade off, which embeds the data into non-zero AC coefficients of quantized DCT blocks and shows that the proposed scheme improves both the visual quality and embedding capacity.
Genuine reversible data hiding technology using compensation for H.264 bitstreams

A Data Hiding Algorithm for H.264/AVC Video Streams Without Intra-Frame Distortion Drift
TLDR
A novel readable data-hiding algorithm, which can embed data into the quantized discrete cosine transform (DCT) coefficients of I frames without bringing any intra-frame distortion drift into the H.264/AVC video host, is presented.

TLDR
A video data embedding scheme in which the embedded signature data is reconstructed without knowing the original host video, which enables a high rate of data embeddedding and is robust to motion compensated coding, such as MPEG-2.
Reversible Steganographic Method with High Payload for JPEG Images
TLDR
The experimental results show that the proposed method can embed twice as much secret data as the irreversible embedding method of Iwata et al. under the same number of embedded sets.
Lossless Watermarking Considering the Human Visual System
TLDR
A novel reversible watermarking technique with higher embedding capacity considering the Human Visual System (HVS) and the distortions in the resulting watermarked image are completely reversible and imperceptible.

TLDR
A simple and effective model of visual between-coefficient contrast masking of DCT basis functions based on a human visual system (HVS) and the new metric, PSNR-HVS-M has outperformed other well-known reference based quality metrics and demonstrated high correlation with the results of subjective experiments.
