Mitosis detection in domain shift scenarios: a Mamba-based approach
This work addresses domain generalization for mitosis detection in medical imaging, which is incremental as it adapts existing methods to a known bottleneck.
The paper tackles mitosis detection in histopathology images under domain shift by proposing a Mamba-based approach using VM-UNet and stain augmentation, but preliminary experiments on the MIDOG++ dataset indicate significant room for improvement without concrete performance numbers.
Mitosis detection in histopathology images plays a key role in tumor assessment. Although machine learning algorithms could be exploited for aiding physicians in accurately performing such a task, these algorithms suffer from significative performance drop when evaluated on images coming from domains that are different from the training ones. In this work, we propose a Mamba-based approach for mitosis detection under domain shift, inspired by the promising performance demonstrated by Mamba in medical imaging segmentation tasks. Specifically, our approach exploits a VM-UNet architecture for carrying out the addressed task, as well as stain augmentation operations for further improving model robustness against domain shift. Our approach has been submitted to the track 1 of the MItosis DOmain Generalization (MIDOG) challenge. Preliminary experiments, conducted on the MIDOG++ dataset, show large room for improvement for the proposed method.
