New loss function enhances medical image segmentation accuracy

Researchers have developed a new loss function called Self-Tuned Boundary-Aware t-vMF Dice Loss (STB-tvMF Dice) to improve medical image segmentation. This method addresses challenges like class imbalance and boundary errors by adapting the similarity function separately for boundary and interior regions without requiring hyperparameter tuning. Experiments showed that STB-tvMF Dice achieved a mean DSC of 70.75% on the Synapse dataset using a U-Net architecture, outperforming the Adaptive t-vMF Dice Loss by over 7 percentage points. AI

IMPACT This research offers a more accurate and efficient method for medical image segmentation, potentially improving diagnostic tools and reducing manual annotation effort.

    Hyperparameter-Free Boundary-Interior t-vMF Dice Loss for Medical Image Segmentation

    arXiv:2610.32266v1 Announce Type: new Abstract: Class imbalance and errors near anatomical boundaries remain challenges in medical image segmentation, motivating loss functions that account for these difficulties. Adaptive t-vMF Dice Loss adjusts the similarity function during tr…
