How to implement IOU for mutli-class image segmentation?

Jun 17, 2020 · IOU Loss function implementation in Pytorch. Antonio_Ossa (Antonio Ossa) June 29, 2020, 11:42am #2. Hi @mayool, I think that the answer is: it depends (as usual). ...

07.11.2016 · A PyTorch implementation of IoU (which I have not tested or used), but seems to be helpful to the PyTorch community. Of course, you can always take my Python/NumPy implementation of IoU and convert it to your own library, language, etc. Happy hacking!

Can someone provide a toy example of how to compute IoU (intersection over union) for semantic segmentation in pytorch?

Jan 15, 2018 · As of 2021, there's no need to implement your own IoU, as torchmetrics comes equipped with it - here's the link. It works with PyTorch and PyTorch Lightning, also with distributed training. From the documentation:
