This project leverages deep learning techniques to automate the classification of rice leaf diseases, specifically targeting bacterial infections. Utilizing a dataset of rice leaf images, we have developed and compared several convolutional neural network (CNN) models, including custom sequential models and advanced architectures like VGG16, VGG19, and Xception. The goal is to achieve high accuracy in disease identification to support agricultural productivity by enabling early detection and treatment of rice leaf diseases.
Rice leaf diseases, particularly those caused by bacteria, pose a significant threat to rice production, impacting food security and farmers' livelihoods globally. Traditional methods of disease identification rely heavily on expert knowledge, which can be time-consuming and not always accessible. Automating disease detection through machine learning offers a scalable, efficient, and cost-effective solution, potentially transforming agricultural practices by facilitating early and accurate disease management.
