Data Hiding and the Statistics of Images [PDF]
, 2009 The fields of digital watermarking, steganography and steganalysis, and content forensics are closely related. In all cases, there is a class of images that is considered "natural", i.e. images that do not contain watermarks, images that do not contain covert messages, or images that have not been tampered with.

Optimal data hiding in H.264/AVC videos for covert communication
, 2009 [[abstract]]A method using an optimal data hiding technique for covert communication via H.264/AVC videos is proposed. An H.264/AVC video consists of a series of I and P image frames.

Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

2006 International Conference on Image Processing, 2006 A new blind data hiding method is proposed based on a novel concept of forbidden zone, where no alteration is allowed in a host signal during message embedding step. Depending on the desired probability of error, the range of the forbidden zone varies, as a compromise between robustness and embedding distortion.

Multilevel Reversible Data Hiding Based on Histogram Modification of Difference Images
, 2009 [[abstract]]Reversible data hiding has drawn considerable attention in recent years. Reversibility allows original media to be completely recovered from marked media without distortion after embedded message has been extracted. In this paper we propose a

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene
Advanced Functional Materials, EarlyView.Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

A capacity-enhanced reversible data hiding scheme based on SMVQ
, 2012 [[abstract]]In recent years, there are many reversible data hiding scheme proposed. Most schemes are guaranteed that the original cover image can be reconstructed completely.

Advanced Functional Materials, EarlyView.Field‐free spin‐orbit torque domain‐wall synapses integrated with stochastic MTJ neurons enable compact hardware Boltzmann machines. Leveraging intrinsic stochasticity and multi‐level conductance, the system achieves efficient probabilistic learning with high accuracy, demonstrating a scalable spintronic platform for energy‐efficient edge AI.
