# SPROUT Preprocessed Datasets

This repository provides the **preprocessed datasets used in SPROUT**:

> **Supervise Less, See More: Training-free Nuclear Instance Segmentation with Prototype-Guided Prompting**
> ICML 2026

Official code repository: https://github.com/Y-Research-SBU/SPROUT

## Datasets

The repository contains preprocessed versions of the following publicly available nuclear segmentation datasets:

* **MoNuSeg**
* **CPM17**
* **TNBC**

The datasets have been reorganized and preprocessed to match the data format expected by the SPROUT codebase.

## Directory Structure

The dataset follows the structure used by SPROUT:

```text
MoNuSeg/
├── train/
│   ├── annotations/
│   ├── images/
│   ├── instances/
│   ├── semantics/
│   ├── png/
│   └── train.txt
└── test/
    ├── annotations/
    ├── images/
    ├── instances/
    ├── semantics/
    ├── png/
    └── test.txt

cpm17/
...

TNBC/
...
```

## Usage

Download or clone the dataset and place the dataset folders under the `data/` directory of the SPROUT repository:

```text
SPROUT/
└── data/
    ├── MoNuSeg/
    ├── cpm17/
    └── TNBC/
```

Then follow the instructions in the official SPROUT repository.


## Data Source

We do **not claim ownership of the original datasets**. MoNuSeg, CPM17, and TNBC were released by their respective authors. This repository only provides reorganized/preprocessed versions of these datasets for reproducibility and convenient use with SPROUT.
