• Abstract: Current methods for pathology image segmentation typically treat 2D slices independently, ignoring valuable cross-slice information. We present PathSeqSAM, a novel approach that treats 2D pathology slices as sequential video frames using SAM2's memory mechanisms. Our method introduces a distance-aware attention mechanism that accounts for variable physical distances between slices and employs LoRA for domain adaptation. Evaluated on the KPI Challenge 2024 dataset for glomeruli segmentation, PathSeqSAM demonstrates improved segmentation quality, particularly in challenging cases that benefit from cross-slice context. We have publicly released our code at https://github.com/JackyyyWang/PathSeqSAM.

  We propose the Dual Consistency SAM (DCSAM) method based on prompttuning to adapt SAM and SAM2 for in-context segmentation. Our key insights are to enhance the features of the SAM's prompt encoder in segmentation by providing high-quality visual prompts. Although the proposed DC-SAM is primarily designed for images, it can be seamlessly extended to the video domain with the support SAM2.
