Typically, the early symptoms of these diseases first appear in roots and leaves, complicating timely detection. This study addresses the challenge of timely and accurate detection of diseases in tomato plants, crucial for effective plant protection management. Conventional manual inspection methods are timeconsuming and subjective, resulting in delays in implementing necessary protection measures. Therefore, an image processing technique and machine learning algorithms were used for rapid and robust detection of diseases in tomato plant leaves, aiming to streamline the detection process for chemical application responses. A dataset containing 250 images of tomato plant leaves were captured under varying light intensities, eye-level angles, and distances. Image augmentation techniques were applied to increase the dataset, resulting in a total of 529 images. These images were converted to LAB color images and then OTSU algorithm was used to segment leaf images and estimate the percentage of affected diseased areas. Various textural features were also extracted from segmented leaf images to create a training dataset. Machine learning algorithms, including Support Vector Machines (SVM), K-Nearest Neighbors (KNN), and decision trees, were trained and evaluated using this dataset to classify images as healthy or diseased. The Quadratic SVM algorithm provided the highest test accuracy of 97.7% for the dataset. This nondestructive processing holds immense promise for improving disease detection efficiency and reducing losses in tomato production, both locally in Bangladesh and globally.  \nABSTRAK  \nDi Bangladesh, budidaya tomat menghadapi tantangan yang signifikan karenakerentanannya terhadap berbagai mikroorganisme, parasit, dan infeksi bakteri.  \nBiasanya, gejala awal penyakit-penyakit ini pertama kali muncul di akar dan daun, sehingga menyulitkan deteksi tepat waktu. Penelitian ini membahas tantangandeteksi penyakit yang tepat waktu dan akurat pada tanaman tomat, yang sangat penting untuk manajemen perlindungan tanaman yang efektif. Metode inspeksi manual konvensional memakan waktu dan subjektif, sehingga mengakibatkan penundaan dalam menerapkan tindakan perlindungan yang diperlukan. Olehkarena itu, teknik pemrosesan gambar dan algoritma pembelajaran mesindigunakan untuk mendeteksi penyakit pada daun tanaman tomat dengan cepat dan kuat, yang bertujuan untuk merampingkan proses deteksi untuk responsaplikasi kimia. Sebuah dataset yang berisi 250 gambar daun tanaman tomatdiambil di bawah berbagai intensitas cahaya, sudut pandang, dan jarak. Teknik augmentasi gambar diterapkan untuk meningkatkan dataset, menghasilkan total 529 gambar. Gambar-gambar ini diubah menjadi gambar berwarna LAB dankemudian algoritma OTSU digunakan untuk mensegmentasi gambar daun dan memperkirakan persent","cbCaiqJQRwqc6kPe","https://ap.wps.com/l/cbCaiqJQRwqc6kPe","pdf",575498,1,9,"English","en",105,"# Introduction\n## Problem background and significance\n## Objectives and approach\n# Materials and Methods\n## Dataset collection and augmentation\n## Image preprocessing, segmentation, and feature extraction\n## Model training and evaluation\n# Results and Discussion\n## Classification performance and accuracy\n## Implications for nondestructive monitoring","[{\"question\":\"Why is early detection of tomato diseases important in Bangladesh?\",\"answer\":\"Early disease symptoms appear on roots and leaves, which complicates timely detection.
