Machine Vision–Based Defect Detection and Quantitative Assessment for Pavement Maintenance

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
An efficient detection and quantification of pavement defects is a significant challenge for intelligent road maintenance; nevertheless, current methodologies exhibit poor accuracy, inadequate lightweight characteristics, and substantial 2D quantification errors. This paper proposes a collection of efficient and lightweight methods.

Cross‐Modal Fusion for 3D Point Cloud and 2D Images in Bridge Defect Inspection

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
As the service life of bridges increases, timely and accurate identification of cracks is essential for ensuring structural safety and durability. Traditional inspection methods often rely on 2D images, which lack reliable depth information for assessing the severity and progression of defects.

A Forward Genetics Strategy for High‐Throughput Gene Identification via Precise Image‐Based Phenotyping of an Indexed EMS Mutant Library

open access: yesAdvanced Science, Volume 12, Issue 47, December 18, 2025.
The GeneHunter‐Gene‐Level Association (GH‐GLA) pipeline enables high‐throughput gene identification in an indexed EMS population of wheat cultivar KN9204. It identifies 5905 trait‐associated wheat genes and validates key regulators of kernel weight and spikelet architecture via gene editing and haplotype analysis.

Image‐Based Estimation of Porosity and Tortuosity in Fibrous Acoustic Absorbers

open access: yesEngineering Reports, Volume 7, Issue 12, December 2025.
A rapid, non‐destructive workflow estimates porosity and tortuosity in fibrous acoustic materials from simple micrographs. Using image segmentation and geometric descriptors, the method achieves sub‐0.3% porosity error and consistent tortuosity ranking, enabling fast material screening and inline quality control without laboratory measurements ...

Multiple Source Cooperation: From Code Division Multiplexing To Variable-Rate Network Coding

open access: yes, 2011
Multiple-source cooperation techniques, including conventional code-division multiplexing (CDM) and classic network coding (CNC), are investigated. We adopt a soft sum - product decoding algorithm for the CNC technique to efficiently process a large ...
