Few-Shot Medical Image Segmentation with High-Fidelity Prototypes

Song Tang, Shaxu Yan, Xiaozhi Qi, Jianxin Gao, Mao Ye, Jianwei Zhang, Xiatian Zhu·June 26, 2024

Summary

The paper presents Detail Self-refined Prototype Network (DSPNet), a novel approach for few-shot medical image segmentation that addresses the issue of local information loss in complex medical images. DSPNet combines high-fidelity prototype construction with foreground (FSPA) and background (BCMA) attention mechanisms to enhance representation. It outperforms state-of-the-art methods on three medical image benchmarks, demonstrating improved segmentation accuracy and adaptability to limited annotated data. The study highlights the importance of self-representation-focused approaches and the use of attention for capturing both global and local semantics, as well as channel-specific structural information, in medical image analysis. The research contributes to the field by offering a robust solution for handling the complexities of medical imaging in scenarios with limited labeled data.
