Coarse-to-Fine Domain Incremental Learning with Attentive Distillation for Mining Footprint Segmentation in Multispectral Imagery
TL;DR
Mapping mining footprints using remote sensing is challenging due to limited fine-grained annotated data. MineC2FNet, a coarse-to-fine domain incremental learning framework, was developed to enhance segmentation by leveraging abundant coarse data.
✦ Why It Matters
Engineers can utilize MineC2FNet to improve segmentation tasks in remote sensing with limited fine-grained data.
Key Takeaways
- Utilize MineC2FNet for improved mining footprint segmentation.
- Leverage coarse data to enhance fine-grained segmentation tasks.
- Explore the new dataset for training and validation purposes.
- Implement attentive distillation techniques in similar applications.
Full Summary
Mining footprint segmentation is crucial for assessing the socio-environmental impacts of mining activities, but fine-grained annotated data is scarce. To tackle this, MineC2FNet was created, utilizing a coarse-to-fine domain incremental learning approach that combines a teacher-student architecture with attentive distillation.
This method selectively transfers knowledge from a coarse domain while refining boundaries using limited fine-grained data. The researchers also introduced a new dataset of 219 images with precise boundary annotations, covering various geographies and commodities.
Extensive testing against state-of-the-art techniques demonstrated that MineC2FNet achieved superior performance, effectively managing domain shifts. The results indicate that leveraging coarse data can significantly improve fine-grained segmentation tasks.
This work has implications for remote sensing applications in environmental monitoring.
