Abstract

Accurate and automated classification of rice grain varieties is important for quality control, authentication, and supply-chain traceability. This paper surveys recent deep-learning approaches and proposes a reproducible framework using deep convolutional neural networks (CNNs) and vision-transformer (ViT) variants for classification of rice grain varieties from images. We describe dataset preparation (public rice image datasets), standardized preprocessing and augmentation, network architectures (transfer learning with EfficientNet/ResNet, custom CNN, and ViT), and evaluation metrics (accuracy, precision, recall, F1, confusion matrices). We summarize performance achieved in recent literature and provide recommended experimental configurations for researchers and practitioners. Finally, we discuss limitations—dataset bias, imaging conditions, and real-world deployment—and outline directions for multimodal and hyperspectral methods to improve robustness.
