A comprehensive review of video steganalysis
IET Image Processing, Volume 16, Issue 13, Page 3407-3425, 13 November 2022., 2022 Abstract Steganography is the art of secret communication and steganalysis is the art of detecting the hidden messages embedded in digital media covers. One of the covers that is gaining interest in the field is video. Presently, the global IP video traffic forms the major part of all consumer Internet traffic. It is also gaining attention in the field

US anti‐suit injunctions and German anti‐anti‐suit injunctions in SEP disputes
The Journal of World Intellectual Property, Volume 25, Issue 2, Page 536-555, July 2022., 2022 Abstract The essay argues that anti‐suit injunctions granted in disputes on standard‐essential patents are inconsistent with the general standards governing anti‐suit injunctions. The section on anti‐suit injunction demonstrates that the case law on anti‐suit injunctions is not comparable to disputes over standard essential patents.

Vision‐oriented algorithm for fast decision in 3D video coding
IET Image Processing, Volume 16, Issue 8, Page 2263-2281, 19 June 2022., 2022 Abstract This paper designs a novel method to reduce the coding complexity of 3D‐HEVC encoder by utilizing the properties of human visual perception. Two vision‐oriented edge detections are proposed: for colour texture detection, the authors adopt the Just‐Noticeable Distortion (JND); for depth map, the authors combine the Sample Adaptive Offset (SAO ...

A novel light field compression framework with hybrid residue transform mechanism
Electronics Letters, Volume 58, Issue 5, Page 207-209, March 2022., 2022 Abstract To meet the challenge of compressing the vast light field data, many prediction‐based algorithms achieve satisfactory results. Although these algorithms remove most redundancy through angular prediction, they rarely develop the suitable de‐correlation solutions for the prediction residue, leading to a large gap for higher compression ...
