Multi‐Scale Transformer for Image Restoration
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]
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
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]
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).
