The authors build an image-classification pipeline that identifies rice varieties from close-up images of individual grains. Transfer-learning image models extract visual patterns, and a second-stage model combines their predictions. On a controlled test of 20 varieties, the authors report 100% accuracy. The result does not establish reliable performance on mixed-grain samples or under varied real-world conditions.

Key insights

• A stacking-based ensemble learning approach significantly enhances classification accuracy and robustness for fine-grained agricultural product identification compared to individual deep learning models.
• Meticulous hyperparameter tuning and regularization of deep learning models are crucial for extracting highly discriminative features and preventing overfitting in complex classification tasks.
• Validation against a comprehensive self-curated dataset and an independent external dataset demonstrates the generalizability and practical applicability of the proposed identification framework.
