Real IRM Images of in vitro Microtubules

This dataset contains real interference reflection microscopy (IRM) images of in vitro microtubules. It is provided in the exact same format as the synthetic SynthMT dataset, enabling seamless switching between real and synthetic data for benchmarking and model development.

• Data type: Real in vitro IRM images containing microtubules
• Format: Identical structure and field names as SynthMT
• Use case: Benchmarking segmentation models, domain adaptation, and biological analysis

Biological Context

Microtubules are cytoskeletal filaments essential for cell biology. IRM enables label-free imaging of microtubules in vitro, providing high-contrast images for quantitative analysis.

Dataset Structure

Each sample contains:

Field	Type	Description
id	string	Unique image identifier
image	Image	Real IRM image (PNG, can be loaded as (512, 512, 3))
mask	Array3D	Instance masks, same as SynthMT, i.e., with shape (C, 512, 512) and uint16 dtype, where C = number of instances in the image. Background pixels = 0.

The structure matches SynthMT, so you can switch the repo key in your code without changes.

Usage Example

Install the Hugging Face datasets library:

pip install datasets

Load the dataset (just change the repo key from SynthMT):

from datasets import load_dataset
import numpy as np

ds = load_dataset("HTW-KI-Werkstatt/IRM-in-vitro-microtubules", split="train")

sample = ds[0]
img_array = np.array(sample["image"].convert("RGB"))
mask_stack = np.stack([np.array(mask.convert("L")) for mask in sample["mask"]], axis=0)
