Abstract

The growing demand for quality in the rice industry has driven innovative solutions for classifying rice varieties, preventing mixtures that impact the final product. This study introduces a convolutional neural network (CNN) for automatic rice grain classification using digital images. A dataset of 75,000 images, divided into five categories ('Ipsala,' 'Arborio,' 'Jasmine,' 'Karacadag,' and 'Basmati'), was used. The model was trained with 80% of the data (56,000 images) and validated with the remaining 20% (14,000 images), using 5,000 new images for final evaluation. The CNN achieved 99.2% accuracy, demonstrating high performance even among visually similar varieties. This approach modernizes traditional methods, improving efficiency and ensuring higher-quality products in the Colombian rice industry.
