Tomato plants, a staple in global agriculture, are highly susceptible to various leaf diseases that can significantly impact both yield and quality. Early detection of these diseases is crucial to mitigate crop losses and reduce the need for extensive pesticide use. Traditional methods of disease identification are labor-intensive and costly, often requiring the expertise of agricultural specialists. However, advancements in machine learning and image processing offer promising solutions for efficient and accurate disease detection. A recent study conducted by researchers at Prince Sultan University[1] introduced a novel feature extraction method using conformable polynomials to detect diseases in tomato leaves. This approach aims to provide an accurate and rapid solution for identifying plant diseases, thereby improving crop yield and food security. The methodology of this study involves several key steps: preprocessing, feature extraction, dimension reduction, and classification. The conformable polynomials method is employed to extract texture features from the images, which are then passed to a classifier. The proposed texture feature is constructed in two parts: the enhanced base term and the texture detail part, which together facilitate detailed textual analysis. The dataset used for this model comprises tomato leaf samples from the Plant Village image dataset. The results demonstrate an impressive 98.80% accuracy in disease detection using the Support Vector Machine (SVM) classifier. This study builds upon earlier research that has explored various methods for diagnosing and classifying tomato leaf diseases. For instance, a previous study utilized Convolutional Neural Networks (CNN) to classify tomato diseases with a 98.49% accuracy[2]. The CNN model processed images by first segmenting the targeted areas and then extracting features such as colors, texture, and edges. Similarly, another study employed a high-resolution portable spectral sensor to detect multi-diseased tomato leaves at different stages, achieving 100% accuracy for healthy leaves[3]. These studies underscore the importance of early and accurate disease detection in improving crop yield and reducing losses. The new study by Prince Sultan University advances this field by introducing a conformable polynomials-based feature extraction method, which enhances the texture analysis of leaf images. This method not only improves the accuracy of disease detection but also speeds up the process, making it more practical for real-world applications. By automating the classification of leaf diseases, farmers can promptly identify and treat affected areas, reducing the need for widespread pesticide application and minimizing environmental impact. In summary, the integration of machine learning and image processing techniques offers a powerful tool for the early detection of tomato leaf diseases. The innovative feature extraction method using conformable polynomials introduced by Prince Sultan University represents a significant step forward in this domain, promising greater accuracy and efficiency in disease management. This approach, combined with previous advancements in the field[2][3], holds the potential to revolutionize agricultural practices and enhance food security worldwide.
