Deep Global Clustering for Hyperspectral Image Segmentation
Analysis
Key Takeaways
- •Proposes Deep Global Clustering (DGC) for memory-efficient hyperspectral image segmentation.
- •DGC learns global clustering from local patches without pre-training, suitable for domain-specific applications.
- •Achieves good performance on leaf disease dataset, demonstrating background-tissue separation and unsupervised disease detection.
- •Identifies optimization instability (cluster over-merging) as a key challenge.
- •Provides code and data for reproducibility.
“DGC achieves background-tissue separation (mean IoU 0.925) and demonstrates unsupervised disease detection through navigable semantic granularity.”
