Content-adaptive reliable robust lossless data embedding
TLDR
This paper proposes an effective solution to RLDE by improving the histogram rotation (HR)-based embedding model and eliminates the ''salt-and-pepper'' noise in HR by the pixel adjustment mechanism, so reliable regions for embedding can be well constructed.About:

Reversible Data Hiding: Advances in the Past Two Decades
TL;DR: In this paper, the various RDH algorithms and researches have been classified into the following six categories: 1) RDH into image spatial domain; 2) RD h into image compressed domain (e.g., JPEG); 3) RDh suitable for image semi-fragile authentication; 4)RDH with image contrast enhancement; 5) RD H into encrypted images, which is expected to have wide application in the cloud computation; and 6) RDD into video and into audio.

Improved wavelet-based watermarking through pixel-wise masking
TL;DR: A new approach to mask the watermark according to the characteristics of the human visual system (HVS) is presented, which is accomplished pixel by pixel by taking into account the texture and the luminance content of all the image subbands.

DCT quantization matrices visually optimized for individual images
TL;DR: Here I show how to compute a matrix that is optimized for a particular image, and custom matrices for a number of images show clear improvement over image-independent matrices.

Lossless data embedding--new paradigm in digital watermarking
TL;DR: This paper introduces a new paradigm for data embedding in images (lossless dataembedding) that has the property that the distortion due to embedding can be completely removed from the watermarked image after the embedded data has been extracted.

A perceptually tuned subband image coder based on the measure of just-noticeable-distortion profile
Chun-Hsien Chou,Yun-Chin Li +1 more
TL;DR: A new quantitative fidelity measure, termed as peak signal-to-perceptible-noise ratio (PSPNR), is proposed to assess the quality of the compressed image by taking the perceptible part of the distortion into account.
