Abstract: To the complex algorithm of traditional plant leaf disease detection, this paper proposed a plant leaf disease detection algorithm based on GLCM texture feature extraction. As the research object of cucumber leaf anthracnose, the K-means clustering algorithm was used to perform image threshold segmentation, and the gray level co-occurrence matrix was used to extract the energy mean, entropy mean, contrast mean and correlation mean of the sample. With the parameter training, the area of disease-free area and diseased area parameters were determined, and then the disease condition of the sample was judged. The results showed that the algorithm had high efficiency and good robustness.
