Image classification is a grouping of images based on specific categories. This study discussed the maize leaf disease image classification using Bag-Of-Features (BOF) approach, which is a collection of methods stages to perform feature extraction and classification of the images. The methods we used were Speeded-Up Robust Features (SURF) for feature extraction, k-means clustering and Support Vector Machine for classification. The maize leaf images used in this research are from the PlantVillage-Dataset. The data consists of 3 types of images: RGB, gray scale and segmentation images. Each type includes 4 disease classes: healthy, cercospora, common rust, and northern leaf blight. There are 50 images for each class. We used 2 scenarios of testing for each type of the data: training and validation; 60 images for training, and the rests (140 images) for validation. Experi-mental results showed that the training accuracies of RGB, gray scale, and segmentation images were 98.25%, 95%, and 74.75% respectively; and the validation accuracies were 72%, 72.75%, and 80.5%.
