This underscores MedSAM’s superior generalization ability, making it a versatile tool in a variety of medical image segmentation tasks. Loss function We used the unweighted sum between cross-entropy loss and dice loss40 as the final loss function since it has been proven to be robust across ...
通过考虑假阴性和假阳性,在使用 Dice 的情况下输出值下降得更多,但交叉熵保持平滑(即,大目标和小目标的 Dice 值为 0.93 和 0.50,而两者的交叉熵损失值为 1.66。) 5 Optimization Function based Improvements Applied to Medical Images 交叉熵损失已广泛应用于各类分割任务中,Miletari等人发现对于分割对象占比较小...
Comparing the estimated and the manually annotated weed plants in the test images the Intersection over Union (Jaccard index) showed mean values in the range of 0.9628 to 0.9909 for the three sampling dates in 2018, and a value of 0.9292 for the one date in 2019. The Dice coefficients ...
条纹和粉红色像素分别表示假阴性和假阳性。对于顶行(即大前景),Dice 损失对于一个假阴性返回 0.96,对于底行(即小目标)对于一个假阴性返回 0.66,而交叉熵损失函数对于这两种情况都输出 0.83。通过考虑假阴性和假阳性,在使用 Dice 的情况下输出值下降得更多,但交叉熵保持平滑(即,大目标和小目标的 Dice 值为 0.93...

Diagnostic accuracy of the deep learning model to differentiate benign from malignant renal masses The segmentation network achieved satisfactory performance in delineating kidney tumor (Fig.2B,E) with a dice similarity coefficient score (DICE) of 0.852 (TableS2). Based on the cropped images, a mult...
dice score of 0.8069 and specificity and sensitivity of 0.9969 and 0.8354, respectively. Additionally, experiments performed on the entire lung volumes indicate promising results, demonstrating that despite being trained only on infected CT images, the model can assist in patient-level lesion ...
Similarly, for Boundary Intersection over Union (IoU), which measures the accuracy of local boundary detail capture, the model trained with Generalised Dice Loss achieved 61.4%, compared to 55.0% for the next best model trained with Compound Loss. These findings suggest that regional loss functions...
. In addition, the Dense-2 U-net had a higher Dice score of 89.2±0.8% for the Central zone (CZ) 76.4±2% for the peripheral zone (PZ) in comparison to the classical U-net with 87.4±1.4% and 74.0±2%, respectively. The results of all statistical measures are compiled in Table1....
