SAUF-Net: Structure--Appearance Representation Learning with Uncertainty Feedback for Semi-Supervised Medical Image Segmentation
TL;DR
SAUF-Net is a novel framework for semi-supervised medical image segmentation that effectively separates structural and appearance features, enhancing segmentation accuracy. It outperforms existing methods, particularly in low-label scenarios, by incorporating uncertainty feedback mechanisms.
✦ Why It Matters
Consider implementing SAUF-Net for your medical image segmentation projects to improve accuracy with fewer labeled samples.
Key Takeaways
- Utilize SAUF-Net for enhanced segmentation in low-label scenarios.
- Implement the Structure--Appearance Decomposition Module for better feature separation.
- Leverage uncertainty feedback to improve model reliability.
- Test on ISIC-2016 and Kvasir-SEG datasets for validation.
How It Works
SAUF-Net employs a Structure--Appearance Decomposition Module (SADM) to separate image features into structural and appearance components. This separation allows the model to focus on stable structural cues while mitigating the impact of appearance variations.
The Disentangled Guidance Module (DGM) then integrates these features into the decoding process, enhancing the model's ability to produce accurate segmentations. Additionally, the dual-head discriminator provides feedback on feature reliability, further refining the segmentation output.
