"name": "HoVer-Net: Nuclear Segmentation and Classification",
"task": "Multi-task Nuclear Segmentation and Classification in H&E Histology",
"description": "A multi-task learning model based on the HoVer-Net architecture that simultaneously performs nuclei segmentation and type classification in H&E-stained histology images. The model processes 256x256 pixel RGB patches and outputs three complementary predictions: binary nuclear segmentation (Dice score: 0.83), hover maps for instance separation, and pixel-level nuclear type classification.",
