DoNet: Deep De-overlapping Network for Cytology Instance Segmentation

1 code implementation CVPR 2023 Hao Jiang, Rushan Zhang, Yanning Zhou, Yumeng Wang, Hao Chen

Cell instance segmentation in cytology images has significant importance for biology analysis and cancer screening, while remains challenging due to 1) the extensive overlapping translucent cell clusters that cause the ambiguous boundaries, and 2) the confusion of mimics and debris as nuclei.
