WebJan 1, 2024 · Commonly used measures to assess automatic contours, such as volumetric Dice Similarity Coefficient (DSC) or Hausdorff distance, have shown to be good measures for geometric similarity, but do not always correlate with clinical applicability of the contours, or time needed to adjust them. This study aimed to evaluate the correlation of new and ... Web$\begingroup$ I'm not sure if Dice is really more intuitive than Jaccard, however there are two distinct differences between the two. Dice does not satisfy the triangle inequality, hence $1-D$ can not properly be used as a metric, while $1-J$ can. inexpensive cities to live in italy https://longbeckmotorcompany.com
