A two-stage video coding framework with both self-adaptive redundant dictionary and adaptively orthonormalized DCT basis

open access: yes, 2015
In this work, we propose a two-stage video coding framework, as an extension of our previous one-stage framework in [1]. The two-stage frameworks consists two different dictionaries.

A Convolutional Neural Network Approach for Half-Pel Interpolation in Video Coding

open access: yes, 2017
Motion compensation is a fundamental technology in video coding to remove the temporal redundancy between video frames. To further improve the coding efficiency, sub-pel motion compensation has been utilized, which requires interpolation of fractional ...

HEVC Watermarking Techniques for Authentication and Copyright Applications: Challenges and Opportunities

open access: yesIEEE Access, 2020
Recently, High-Efficiency Video Coding (HEVC/H.265) has been chosen to replace previous video coding standards, such as H.263 and H.264. Despite the efficiency of HEVC, it still lacks reliable and practical functionalities to support authentication and ...

Multi‐Scale Transformer for Image Restoration

open access: yesCAAI Transactions on Intelligence Technology, Volume 11, Issue 1, Page 41-54, February 2026.
ABSTRACT Although Transformer‐based image restoration methods have demonstrated impressive performance, existing Transformers still insufficiently exploit multiscale information. Previous non‐Transformer‐based studies have shown that incorporating multiscale features is crucial for improving restoration results.

Extended Cross-Component Prediction in HEVC [PDF]

open access: yes2015 Picture Coding Symposium (PCS), 2015
The support for chroma formats other than 4∶2∶0 and bit depths higher than 10 bit has been included into the High Efficiency Video Coding (HEVC) standard by the publication of Version 2. In contrast to 4∶2∶2 profiles without additional dedicated coding tools relative to the Main profile, all 4∶4∶4 profiles specify a novel compression efficiency tool ...

Seeing Gusty Winds: Optical Tracking of Tree Motion Captures Peak 3‐s Gust Velocities

open access: yesMeteorological Applications, Volume 33, Issue 1, January/February 2026.
Our proof‐of‐concept shows that short video clips of trees and flags, analysed to detect their motions, potentially provide a low‐cost method to estimate peak 3‐s wind gusts. Such measurements offer insights into local wind hazard variations without the need for complex instrumentation, with future use envisaged in insurance risk assessment.

Improved intra mode signaling for HEVC [PDF]

open access: yes2011 IEEE International Conference on Multimedia and Expo, 2011
In the current development of HEVC, compression performance improved significantly compared to H.264/AVC for both inter pictures and intra pictures. With intra compression, the main reason for this improvement is the large increase in intra prediction directions (up to 34).
