Early Merge mode decision algorithm for 3D-HEVC based on learning model

Tongxin xuebao, 2019
3D-high efficiency video coding (3D-HEVC) standard is an extension of HEVC.Though 3D-HEVC effectively improves the compression efficiency of 3D video,it also brings huge computational complexity.To greatly reduce the 3D-HEVC coding complexity,an early ...

Subjective assessment of visual fidelity: Comparison of forced‐choice methods

Journal of the Society for Information Display, Volume 32, Issue 10, Page 726-740, October 2024.
We compared two subjective test paradigms (ISO/IEC 29170‐2 flicker, single frame non‐flicker) for evaluation of visually lossless compression in 3D images and video. Overall, the flicker paradigm was more sensitive than non‐flicker methods, but it may overestimate artifact visibility in natural conditions. The increased sensitivity of flicker detection

Pre‐trained low‐light image enhancement transformer

IET Image Processing, Volume 18, Issue 8, Page 1967-1984, 19 June 2024.
An effective transformer‐based low‐light image enhancement solution called low‐light image enhancement transformer, pre‐trained on a large synthesized low/normal light image dataset, which achieves state‐of‐the‐art performance, is proposed. The model combines convolutional neural network and transformer architectures for robust feature extraction at ...

High efficiency compression for object detection

, 2018
Image and video compression has traditionally been tailored to human vision. However, modern applications such as visual analytics and surveillance rely on computers seeing and analyzing the images before (or instead of) humans.

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.
