# Models

I use this page to collect model and dataset resources connected to Petri-dish imaging, colony segmentation, dish detection, and CFU counting workflows.

## grayleafspot

**grayleafspot** PyTorch U-Net models for gray leaf spot (*Magnaporthe* and related fungal) colony segmentation on 90 mm petri-dish images.

## Petri Dish YOLO ONNX

**Petri Dish YOLO ONNX** detects round Petri dishes in camera images and returns bounding-box locations for each detected dish.

## CFU Colony Object Detection Models

**CFU Colony Object Detection Models** are gated PyTorch model artifacts trained to detect CFU colonies on Petri dishes for colony counting workflows.

Access: The CFU count model repository is gated and requires approval before model files can be downloaded.
