## 📚 Introduction
**XHRBench** evaluates fine-grained perception and complex reasoning in multimodal large language models using ultra-high-resolution remote-sensing imagery. This repository retains the name **XHRBench** and belongs to the same RSHR benchmark project as [RSHR-Bench](https://huggingface.co/datasets/RL-MIND/RSHR-Bench), with a different file layout.
The full benchmark described in the paper contains **5,329 full-scene images**, with a long side of at least **4,000 pixels** and up to approximately **3 × 10⁸ pixels (300 MP)** per image. This repository's `dataset.json` contains **1,932 VQA examples**; the package's example count is distinct from the full benchmark's image count.
## 🎯 Dataset at a Glance
| Item | Details |
| --- | --- |
| Current JSON release | 1,932 VQA examples |
| Task categories | 17 original category identifiers |
| Images per example | 1 image: 1,862; 2 images: 50; 3 images: 20 |
| Data language | English |
| Main files | `dataset.json`, `images/`, `data/train-00000-of-00001.parquet` |
| Full benchmark scope | 5,329 full-scene images; 9 perception categories and 4 reasoning types |
The benchmark draws on **DOTA-v2.0, MiniFrance, FAIR1M, HRSCD, XLRS-Bench**, and the team's **100 MP UAV imagery**. Its two-stage **Human–LLM Adversarial Verification** pipeline combines LLM adversarial filtering with human review to reduce questions answerable from language priors alone.
## 🌟 Task Design
| Task family | Evaluation focus |
| --- | --- |
| Multiple-Choice VQA (MCQ) | Visual decisions within a fixed answer space, including single-turn and multi-turn dialogues |
| Open-Ended VQA (OEQ) | Free-form visual understanding and compositional reasoning |
| Image Captioning (IC) | Global scene summaries and regional descriptions |
| Single-Image Evaluation (SIE) | Multi-scale perception and reasoning within an ultra-high-resolution image |
These four families describe the full evaluation design in the paper. The `dataset.json` in this repository contains VQA annotations with answer options. See the [paper](https://arxiv.org/abs/2512.17319) and [code](https://github.com/Yunkaidang/RSHR) for the complete evaluation protocol.
## 📦 Data Format
```text
dataset.json # List of VQA annotations
images/ # Original images referenced by annotations
data/train-00000-of-00001.parquet # Repository-provided Parquet file
assets/ # Dataset-card figures and logos
```
| Field | Description |
| --- | --- |
| `id` | Sample identifier |
| `images` | List of relative image paths |
| `question` | Question text |
| `options` | Mapping from option letters to option text |
| `answer` | Gold answer option |
| `category` | Original task category identifier |
Image paths are relative to the repository root. Category identifiers retain their original spelling. The `train` component in the Parquet filename is a packaging label; it does not by itself define the paper's training/test protocol.

| `multi_region_join_contrast` | 20 |
| `multi_region_join_contrast_singal` | 50 |
| `multitrun-future_prediction` | 150 |
| `multiturn_object_state_judgement` | 132 |

## 🚀 Quick Start
Inspect the annotations first, then download the images you need.
```python
import json
from huggingface_hub import hf_hub_download
annotation_path = hf_hub_download(
repo_id="RL-MIND/XHRBench",
repo_type="dataset",
filename="dataset.json",
)
with open(annotation_path, encoding="utf-8") as f:
samples = json.load(f)
sample = samples[0]
print(sample["category"], sample["question"], sample["options"])
# Download only the image needed for this sample.
image_path = hf_hub_download(
repo_id="RL-MIND/XHRBench",
repo_type="dataset",
filename=sample["images"][0],
)
```
## 📊 Evaluation and Visualizations
The original project reports evaluations of **14 models**, including GPT-4o, Gemini 1.5 Pro, Qwen2.5-VL, and remote-sensing models such as GeoChat and VHM, across multiple-choice VQA, open-ended VQA, and image captioning. The original overview, leaderboard, and task-distribution figures are retained below; consult the paper for model versions and evaluation settings.

## 💡 Usage Notes
- Intended for evaluating visual understanding, perception, and reasoning in ultra-high-resolution remote sensing.
- Original high-resolution images can require substantial disk space and decoding memory; download them selectively when possible.
- Use `dataset.json` together with `images/` and preserve the relative paths.
- This repository and RSHR-Bench use different packages. File and shard counts should not be used as direct measures of benchmark size.
## 📜 License and Citation
The repository declares the **Apache-2.0** license. The imagery draws on other public remote-sensing datasets; consult the original licenses and terms when using those source datasets.
