Dual Co-Train framework boosts ultrasound tongue segmentation with limited data

Researchers have developed a novel framework called Dual Co-Train for improving ultrasound tongue segmentation, particularly in scenarios with extremely limited labeled data. This source-free domain adaptation method utilizes a lightweight UltraUNet backbone and refines pseudo-labels for unlabeled target data. The system also generates synthetic target-style image-mask pairs using a conditional GAN, enabling closed-loop adaptation without requiring access to the original source data. Evaluations across multiple datasets and transfer pairs demonstrate that Dual Co-Train significantly enhances segmentation overlap and contour accuracy compared to existing baseline methods. AI

IMPACT Enhances segmentation accuracy in medical imaging with minimal labeled data, potentially improving diagnostic tools.

    Dual Co-Train: Cross-Dataset Ultrasound Tongue Segmentation Under Extreme Data Scarcity

    arXiv:2608.17983v1 Announce Type: cross Abstract: Ultrasound tongue contour segmentation remains challenging under cross-dataset domain shift, where limited annotations, probe variability, and acquisition noise often degrade model generalization. We present a source-free domain a…
