Zebrafish Morphology and Segmentation - BrightField

The Ramona MCAM supports fully automated segmentation of zebrafish from both single-frame and stack datasets. Users can choose from seven segmentation models—body, eyes, otolith, pericardium, tail, and yolk sac—or apply all models simultaneously. The analysis produces a CSV file containing the measured area for each selected model. For additional details on the underlying mechanics of the segmentation workflow, please refer to the MCAM User Manual.
