MDCK fluorescence microscopy dataset

Summary

This dataset contains multi-channel fluorescence images of MDCK epithelial cells acquired on a Nikon ECLIPSE Ti2 inverted microscope using a Nikon CFI Plan Apo 60x 1.4 NA oil immersion objective. The release includes raw Nikon ND2 files and the processed ground-truth training patches used in our end-to-end learning pipeline.

Preview image: For quick visualization. Should not be used for quantitative analysis. For analysis, use the raw ND2 files and the processed patches.
