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.

Improved intra mode signaling for HEVC [PDF]

2011 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).

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.

Area efficient DST architectures for HEVC [PDF]

2017 13th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME), 2017
This work analyses the actual throughput of the Discrete Sine Transform (DST) stage in a realistic HEVC encoder, which executes the rate-distortion optimization algorithm to achieve high compression quality. Then, a low complexity DST factorization, where all the integer multiplications are substituted with add-and-shift operations, is exploited to ...

SFNIC: Hybrid Spatial‐Frequency Information for Lightweight Neural Image Compression

CAAI Transactions on Intelligence Technology, Volume 10, Issue 6, Page 1717-1730, December 2025.
ABSTRACT Neural image compression (NIC) has shown remarkable rate‐distortion (R‐D) efficiency. However, the considerable computational and spatial complexity of most NIC methods presents deployment challenges on resource‐constrained devices. We introduce a lightweight neural image compression framework designed to efficiently process both local and ...

Adaptive Parallelization Based on Frame‐Level and Tile‐Level Parallelisms for VVC Encoding

Concurrency and Computation: Practice and Experience, Volume 37, Issue 25-26, 30 November 2025.
ABSTRACT To meet the growing demand for high‐efficiency video compression standards, Versatile Video Coding (VVC) has been developed as a successor to High Efficiency Video Coding (HEVC). VVC offers approximately a 50% reduction in bitrate compared to HEVC while maintaining comparable visual quality.
