Multi‐Scale Transformer for Image Restoration

CAAI 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.

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

Meteorological 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.
