Hyperspectral Grading of Rice Blast Severity (0–5) Using Regional Spectral-Angle Features and Heterogeneous Stacking (XGBSVMRF-SA)

Rice blast caused by Pyricularia oryzae progresses from symptom-free leaves to extensive tissue death, while neighboring severity grades often show similar spectra. This study developed XGBSVMRF-SA to integrate regional spectral-angle (SA) features with heterogeneous stacking of XGBoost 3.1.2, support vector machine, a...
