Forgery localization in images based on joint statistics of image blocks with neighbouring blocks
IET Image Processing, 2021 Flawless image forensic analysis necessitates precise identification of tampering regions in digital images along with the determination of state of an image (original or forged). Most of the efforts towards localization of forgeries involve localization

H.266/VVC fast intra prediction using Sobel edge features
Electronics Letters, 2021 Versatile video coding is the next‐generation video coding standard. Compared with the previous high efficiency video coding standard, versatile video coding reduces 30% or more bitrate but requires significantly higher encoding complexity.

Low-complexity lossless codes for image and video coding [PDF]
SPIE Proceedings, 2010 We describe design of lossless block codes for geometric, Laplacian, and similar distributions frequently arising in image and video coding. Proposed codes can be understood as a generalization of Golomb codes, allowing more precise adaptation to values of parameters of distributions, and resulting in lower redundancy.

Low-Complexity Loeffler DCT Approximations for Image and Video Coding
Journal of Low Power Electronics and Applications, 2018 This paper introduced a matrix parametrization method based on the Loeffler discrete cosine transform (DCT) algorithm. As a result, a new class of 8-point DCT approximations was proposed, capable of unifying the mathematical formalism of several 8-point ...

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin
Molecular Oncology, EarlyView.The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.
