# MM-RIS: Multimodal Referring Image Segmentation Dataset

The **MM-RIS** dataset was introduced in the paper [RIS-FUSION: Rethinking Text-Driven Infrared and Visible Image Fusion from the Perspective of Referring Image Segmentation](https://huggingface.co/papers/2509.12710).

This large-scale benchmark supports the multimodal referring image segmentation (RIS) task by providing a goal-aligned approach to supervise and evaluate how effectively natural language contributes to infrared and visible image fusion outcomes.

## Code

The official code repository for the associated RIS-FUSION project can be found on GitHub: [https://github.com/SijuMa2003/RIS-FUSION](https://github.com/SijuMa2003/RIS-FUSION)

## Introduction

Text-driven infrared and visible image fusion has gained attention for enabling natural language to guide the fusion process. However, existing methods often lack a goal-aligned task to supervise and evaluate how effectively the input text contributes to the fusion outcome.

We observe that **referring image segmentation (RIS)** and text-driven fusion share a common objective: highlighting the object referred to by the text. Motivated by this, we propose **RIS-FUSION**, a cascaded framework that unifies fusion and RIS through joint optimization.

To support the multimodal referring image segmentation task, we introduce **MM-RIS**, a large-scale benchmark with **12.5k training** and **3.5k testing** triplets, each consisting of an infrared-visible image pair, a segmentation mask, and a referring expression.

## Dataset Structure

The MM-RIS dataset is available in this Hugging Face repository and consists of the following Parquet files:

- `mm_ris_test.parquet`
- `mm_ris_val.parquet`
- `mm_ris_train_part1.parquet`
- `mm_ris_train_part2.parquet`

These files together comprise 12.5k training and 3.5k testing triplets. Each triplet includes an infrared image, a visible image, a segmentation mask, and a natural language referring expression.

## Sample Usage

To prepare the MM-RIS dataset for use with the RIS-FUSION code, you will need to download all the dataset files from this repository and merge the training partitions.

1.  **Download the dataset files**:
    Download `mm_ris_test.parquet`, `mm_ris_val.parquet`, `mm_ris_train_part1.parquet`, and `mm_ris_train_part2.parquet` from this Hugging Face repository and place them under a `data/` directory in your project, ideally within a cloned RIS-FUSION GitHub repository.

2.  **Merge partitioned parquet files**:
    The RIS-FUSION GitHub repository provides a script to merge the partitioned training data. Assuming you have cloned the repository and placed the parquet files in `./data/`:

    ```bash
    python ./data/merge_parquet.py
    ```
    This script will combine `mm_ris_train_part1.parquet` and `mm_ris_train_part2.parquet` into a single `mm_ris_train.parquet` file.

Once the dataset is prepared, you can use it for training and testing models as shown in the examples below.
