Chickpea wilt is a widespread agricultural disease that affects production worldwide every year. Rapid and accurate detection of the disease is desirable, but is difficult using traditional methods. Therefore, it is necessary to detect the disease using automatic, rapid, reliable, and simple methods before it completely damages the plant. Herein, we investigate the applicability of machine learning-based texture analysis methods to determine the severity level of Fusarium wilt in chickpea. Various procedures, such as image annotation, augmentation, resizing, and color conversion using different color spaces (RGB, HSV, and Lab*), were performed to develop the model. To perform texture feature extraction, the Gray-Level Run-Length Matrix (GLRLM) and the Gray-Level Occurrence Matrix (GLCM) feature extraction methods were used. To avoid local minima, Bayesian optimization was applied, while to train and test the effectiveness of the proposed model, 15000 images (70–20-10 ratio for training, validation and testing) were used. Finally, multi-class classification models were developed using image classification methods such as K-Nearest Neighbors (KNN), Support Vector Machine (SVM), and Neural Networks. The proposed GLRLM-HSV based KNN model performed well in determining the severity level of fusarium wilt of chickpea among five different severity levels, with an accuracy of 94.5%.
