Notes

Sachi provided a demo of the latest version of Monai Label with QuPath (not with Hovernet yet). Initial experiments show that HoverNet is significantly slower for larger ROIs - especially on lower-end GPUs, but this is to be expected in this first release. Jonny suggested that the next pipeline that we focus on should be Tissue/Lesion Segmentation, which would complement the more computationally challenging nuclei segmentation. Reasons for this would be:

• Providing scope to apply some of the 2D techniques already developed for 2D radiology use-cases (e.g. DeepEdit)
• Complementary to the existing nuclei segmentation pipeline
• Much faster to compute - so better for GUI interactivity We should identify some clinically relevant use-cases rather than just providing an algorithm.

Lee & Jeff concurred with this direction.

Lee suggested that MONAI could offer pretrained unsupervised task weights - perhaps trained on TCGA (need to check licence restrictions).

Lee mentioned that there is an issue with CuCIM (#370). Gregory & Gigon are somewhat time-bound with other commitments until the new year.
