PGVMS: A Prompt-Guided Unified Framework for Virtual Multiplex IHC Staining with Pathological Semantic Learning

The paper presents PGVMS, a prompt-guided unified framework that overcomes limitations in virtual multiplex IHC staining by employing adaptive prompt guidance, protein-aware learning, and prototype-consistent learning to generate accurate, spatially aligned multi-stain representations from H&E images using only uniplex training data.

Retrieve and Segment: Are a Few Examples Enough to Bridge the Supervision Gap in Open-Vocabulary Segmentation?

This paper proposes a retrieval-augmented test-time adapter that leverages a few-shot support set of pixel-annotated images to fuse textual and visual features, effectively bridging the performance gap between zero-shot and fully supervised open-vocabulary segmentation while preserving the ability to recognize arbitrary categories.
