This repository contains a StarDist deep learning model designed for segmenting MiaPaCa2 cells from the CD44 channel in fluorescence microscopy images. The model is capable of accurately segmenting individual MiaPaCa2 cells while excluding HUVECs. Trained on a small dataset, the model achieved an Intersection over Union (IoU) score of 0.884 and an F1 Score of 0.950, indicating high precision in cell segmentation. Specifications Model: StarDist for segmenting MiaPaCa2 cells from the CD44 fluorescence channel Training Dataset: Number of Images: 8 paired fluorescence microscopy images and label masks Microscope: Spinning disk confocal microscope (3i CSU-W1) with a 20x objective, NA 0.8 Data Type: Fluorescence microscopy images of the CD44 channel, obtained after immunofluorescence staining with primary and secondary antibodies and manually segmented masks File Format: TIFF (.tif) Fluorescence Images: 16-bit Masks: 8-bit Image Size: 920 x 920 pixels (Pixel size: 0.6337 x 0.6337 µm²) Model Capabilities: Segment MiaPaCa2 Cells: Accurately detects individual MiaPaCa2 cells while ignoring HUVECs Measure CD44 Intensity: Allows for the measurement of CD44 intensity around MiaPaCa2 cells, specifically from the CD44 channel Performance: Average IoU: 0.884 Average F1 Score: 0.950 Model Training: Conducted using ZeroCostDL4Mic (https://github.com/HenriquesLab/ZeroCostDL4Mic/wiki) Reference Biorxiv paper
