Dice Coefficient
A metric that measures the degree of overlap between two regions. It is commonly used in medical image segmentation and is robust to class imbalance.
Timeline (last 90 days)
The Dice coefficient is defined as twice the intersection area divided by the sum of the areas of the two regions, and is highly mathematically correlated with IoU, but Dice is more robust to class imbalance, and when the target region is much smaller than the background region, Dice is usually more suitable than IoU as the primary evaluation metric.
Medical image segmentation tasks are typically evaluated using metrics such as the Dice coefficient and Hausdorff distance to measure boundary overlap and shape conformity.
