  We describe here the panoptic segmentation method we devised for our
participation in the CoNIC: Colon Nuclei Identification and Counting Challenge
at ISBI 2022. Key features of our method are a weighted loss specifically
engineered for semantic segmentation of highly imbalanced cell types, and a
state-of-the art nuclei instance segmentation model, which we combine in a
Hovernet-like architecture.
