SEAM-YOLO: Lightweight Detection of Lithium Mineral Phases in Microscopy Images Using YOLOv12
Revolutionizing Mineral Detection with AI-Powered Precision
This paper introduces SEAM-YOLO, a novel lightweight object detector specifically designed for identifying lithium mineral phases in microscopic images. It achieves a mAP50 of 99.4% and an inference rate of 119 FPS with only 2.46 million parameters, significantly outperforming the YOLOv12 baseline. The model incorporates three key innovations: C3K2-Faster-EMA for optimized feature enhancement, a Spatial-Channel Enhancement Attention Module (SEAM) in the detection head for improved texture feature extraction, and CARAFE upsampling for precise reconstruction of small-scale features. This makes SEAM-YOLO a highly efficient and accurate solution for real-time industrial mineral detection.

The proposed SEAM-YOLO builds upon YOLOv12n, integrating PConv, EMA, SEAM, and CARAFE for specialized mineral image analysis. Its design maintains the backbone, neck, and head structure while customizing key modules for improved performance.
The C3K2-Faster-EMA module combines Partial Convolution (PConv) and Efficient Multi-scale Attention (EMA) to reduce computational complexity by 35% and optimize channel-wise feature discrimination. This enhances feature discriminability while maintaining efficiency.
The SEAM (Spatial-Channel Enhancement Attention Module) is embedded in the detection head, leveraging spatial-channel collaborative weighting. It significantly improves the fine-grained extraction of lithium mineral texture features, crucial for complex mineral images.
The CARAFE upsampling operator replaces conventional methods in the Feature Pyramid Network (FPN). It dynamically generates content-aware upsampling kernels, boosting the reconstruction precision of small-scale lithium mineral features and adapting to edge contours and texture distributions.
An ablation study systematically integrated the three modules. C3K2-Faster-EMA reduced parameters by 9.6% while maintaining accuracy. SEAM significantly improved inference efficiency (FPS increase). CARAFE boosted mAP50 by 0.8% for small targets. The combined SEAM-YOLO achieved 99.4% mAP50, a 1.9% improvement over baseline, with 1.6% fewer parameters.
SEAM-YOLO was benchmarked against lightweight YOLO models (YOLOv5n, YOLOv7-tiny, YOLOv8n, YOLOv9n, YOLOv10n, YOLOv11n, YOLOv12n, YOLOv13n). It achieves 99.4% mAP50 (2.0% better than YOLOv13n, 1.9% better than YOLOv12n) with 5.4G FLOPs and 119 FPS, offering an optimal balance of accuracy, speed, and lightweight design for industrial applications.
SEAM-YOLO operates at 119 FPS, achieves 99.4% mAP50, and has only 2.46 million parameters, demonstrating superior efficiency and accuracy for real-time mineral detection tasks. This makes it a robust solution for complex industrial environments.
SEAM-YOLO provides a practically viable technical solution for real-time lithium mineral detection in industrial applications, addressing challenges of high variability in morphology, size, and texture, and meeting dual constraints of computational efficiency and deployment cost.
Future work includes integrating adaptive illumination enhancement, adversarial training, meta-learning, domain adaptation for rare mineral morphologies, and developing a unified multi-mineral recognition framework with purity assessment functionality.
