Considering the human population, food is one of the major problems Sri Lanka might face in the near future. Rice is the most widely consumed food product and one of the extensively cultivated crops in Sri Lanka. Therefore, increasing the crop yield is one of the primary needs of the country. When rice crops are infected with diseases, it results in a loss of crops. Therefore, it is essential to identify the disease in the early stage of infection to prevent the damage that can be done. Disease identification could be challenging without a clear understanding. With the advancement of new technologies, researchers are interested in identifying paddy diseases through machine learning and image processing techniques to help farmers identify infectious diseases accurately. It is difficult to observe the paddy leaf with the naked eye to diagnose the infected disease. In this research, an algorithm was developed to check whether the image contains different changes to the paddy leaf by considering the green colour pixels and their variance. OpenCV libraries have been used to develop the algorithm for feature extraction. Those features were used as attributes to the LightGBM algorithm to classify the disease images with over 80% accuracy.
