One compelling reason for using cross-entropy over dice-coefficient or the similar IoU metric is that the gradients are nicer. The gradients of cross-entropy wrt the logits is something like p − t, where p is the softmax outputs and t is the target. Meanwhile, if we try to write the dice coefficient in a differentiable form: 2 p t p 2 + t ...

WebMay 21, 2024 · Another popular loss function for image segmentation tasks is based on the Dice coefficient, which is essentially a measure of overlap between two samples. This measure ranges from 0 to 1 where a Dice coefficient of 1 denotes perfect and complete overlap. The Dice coefficient was originally developed for binary data, and can be … WebJun 19, 2024 · I have formulated a model that outputs pretty descent segmented images by decreasing the loss value. However, I cannot evaluate the model performance in metrics, such as meanIoU or Dice coefficient. In case of binary semantic segmentation it was easy just to set the threshold of 0.5, to classify the outputs as an object or background, but it ...
