LLS-SevEst – Late leaf spot severity estimator. A machine learning approach to assessing Nothopassalora personata in peanut por Herrador, Tiago A., Migotti Scaglia, Juliana, Paredes, Juan Andrés, Cazon, Luis Ignacio

“…The threshold-based model yielded high false positive rates due to its inability to account for natural leaf variation, while the morphological preprocessing method improved segmentation marginally but still required manual adjustments. The K-means clustering approach provided relatively better segmentation performance under the specific conditions tested and showed high potential for automated and reproducible disease severity estimation. …”
