22.03.2019 · I’m doing a semantic segmentation problem where each pixel may belong to one or more classes. However, I cannot find a suitable loss function to compute binary crossent loss over each pixel in the image. BCELoss requires a single scalar value as the target, while CrossEntropyLoss allows only one class for each pixel. Is there any built-in loss for this …
14.12.2019 · For calculating the SDS for every class we multiply the (pred score * target score) and divide by the sum of (pred²+target score²). Image Inside every epoch for all the batch we calculate the dice...
13.06.2020 · I basically have two masks but I do not know how to prepare it for a semantic segmentation model like DeepLab and U-Net.It has 5 classes (not including the background) Color Mask Mask Is there a Pytorch function to transform the mask into something readily digestible by the model? My model output is [batcth_size, n_channels, height, width]. What …
