The document discusses using image processing techniques to predict plant diseases. It begins with an introduction describing the importance of identifying plant diseases early to reduce crop losses. It then discusses related work where researchers have used techniques like convolutional neural networks (CNNs) to classify plant leaf images with over 98% accuracy. The document outlines the proposed system's architecture, which involves preprocessing images, segmenting leaves, extracting features, and using CNNs for classification. It presents the methodology and experimental results, achieving high accuracy in detecting tomato plant diseases. In conclusion, it states that early detection of diseases using this approach can reduce costs and time compared to manual identification.
