Motion vector‐domain video steganalysis exploiting skipped macroblocks

IET Image Processing, Volume 18, Issue 5, Page 1132-1144, 17 April 2024.
This paper proposes a novel 11‐dimensional feature set to detect MV‐based video steganography. The feature set includes two components. The first is the probability distribution of motion vector prediction (MVP) difference, and the second is the probability distribution of partition state transfer.

Dynamic estimator selection for double‐bit‐range estimation in VVC CABAC entropy coding

IET Image Processing, Volume 18, Issue 3, Page 722-730, 28 February 2024.
A selection method to determine which estimator is recommended to dynamically perform the current entropy coding. Taking advantage of the double‐bit‐range architecture, we also rearrange the bits contained in the different estimators based on MPS determination and Least Probable Symbol LPS considerations.
