REW-DETR: A Lightweight Real-Time Detection Transformer for Bridge Surface Defect Detection

Timely detection of bridge surface defects is important for structural safety assessment and inspection efficiency. To address defect scale variation, complex background interference, and the high computational cost of RT-DETR-R50, this study proposes REW-DETR, a lightweight bridge surface defect detector. REW-DETR ado...

Comparative Evaluation of UAV Multispectral and Measured Biophysical Feature Combinations for Winter Wheat Canopy Nitrogen Estimation

Accurate estimation of winter wheat canopy nitrogen concentration (CNC) supports crop diagnosis and precision nitrogen management, yet the relative value and redundancy of multispectral, structural, and chlorophyll-related variables remain unclear in small dat asets. Using 155 multi-temporal observations retained from...

Cross-Site Prediction of Soil Organic Carbon in Plantation Forests Using Vis-NIR Spectroscopy and Target-Spectrum-Guided Source-Domain Weighting

Soil organic carbon (SOC) is an important indicator of plantation-forest soil quality, but Vis-NIR models calibrated at one site may show systematic bias at another. This study used 370 Gaofeng samples as the source domain and 119 Yachang samples as the target domain to evaluate SOC-gradient-constrained spectral simila...
