Estimation of potato leaf chlorophyll content using machine learning and UAV-based multimodal data fusion with Boruta-SHAP feature optimization

Mingbo Bian, Haikuan Feng, Riqiang Chen, Yiguang Fan et autres

Accurate estimation of leaf chlorophyll content (LCC) is critical for monitoring crop physiological status and supporting precision management. This study proposes a multimodal regression framework that integrates unmanned aerial vehicle (UAV)-based hyperspectral and RGB imagery with ground-measured LCC data for estimating potato …

Hyperspectral inversion of winter wheat nitrogen content based on feature optimization and stacking ensemble learning

Fuxing Guan, Changchun Li, Guijun Yang, Yinghua Jiao et autres

Rapid, non-destructive crop nitrogen monitoring is a core pillar of precision fertilization and mass-balance nutrient management, which requires real-time uptake data to balance fertilizer inputs, crop demand and environmental nitrogen losses. But hyperspectral data redundancy, background noise and black-box machine learning models …

Interpretable machine learning and causal inference for maize LAI estimation from UAV multimodal imagery

Liang Han, Guijun Yang, Jintao Wu, Pengzhi Cui et autres

Accurate retrieval of leaf area index (LAI) is vital for crop monitoring and genetic breeding. Although multi-modal unmanned aerial vehicle (UAV) remote sensing has advanced LAI estimation, conventional empirical models often overfit on small breeding populations and cannot disentangle the true causal …
