A Single-organoid Workflow for quantitative Imaging classiFication and Tracking (SWIFT)

Abstract SWIFT (Single-organoid Workflow for quantitative Imaging classiFication and Tracking) is a fast and modular pipeline for quantitative, time-resolved organoid analysis from brightfield images. Requiring only minimal training annotations, SWIFT combines YOLOv8, SAM, and application-specific object classification to deliver accurate single-organoid segmentation, phenotyping, and tracking. The workflow is robust across organoid types and microscope systems. Applied to intestinal organoids, SWIFT uncovers dynamic Wnt-dependent morphological transitions, enabling scalable, high-throughput studies of epithelial plasticity.
