# ZoomEye: Enhancing Multimodal LLMs with Human-Like Zooming Capabilities through Tree-Based Image Exploration

This repository contains the evaluation data for **ZoomEye**, a method presented in the paper [ZoomEye: Enhancing Multimodal LLMs with Human-Like Zooming Capabilities through Tree-Based Image Exploration](https://huggingface.co/papers/2411.16044).

ZoomEye proposes a training-free, model-agnostic tree search algorithm tailored for vision-level reasoning. It addresses the limitations of existing Multimodal Large Language Models (MLLMs) that operate on fixed visual inputs, especially when dealing with images containing numerous fine-grained elements. By treating an image as a hierarchical tree structure, ZoomEye enables MLLMs to simulate human-like zooming behavior, navigating from root to leaf nodes to gather detailed visual cues necessary for accurate decision-making.

This dataset supports the evaluation of MLLMs on a series of high-resolution benchmarks, demonstrating consistent performance improvements for various models.

## Evaluation Data Preparation

The core evaluation data (including V* Bench and HR-Bench) used in the ZoomEye paper has been packaged together.

1.  **Download Data**: The evaluation data is provided [here](https://huggingface.co/datasets/omlab/zoom_eye_data). After downloading, please unzip it. The path to the unzipped data is referred to as **`<anno path>`**.

2.  **[Optional] MME-RealWorld Benchmark**: If you wish to evaluate ZoomEye on the MME-RealWorld Benchmark, follow these steps:
    *   Follow the instructions in [this repository](https://github.com/yfzhang114/MME-RealWorld) to download the images.
    *   Extract the images to the `<anno path>/mme-realworld` directory.
    *   Place the `annotation_mme-realworld.json` file from [this link](https://huggingface.co/datasets/omlab/zoom_eye_data) into `<anno path>/mme-realworld`.

### Folder Tree
The expected folder structure after preparation is as follows:

```
zoom_eye_data

  │   └── annotation_hr-bench_4k.json

```

## Sample Usage

### 1. Run the Python Demo

We provide a demo file of Zoom Eye accepting any input Image-Question pair. The zoomed views of Zoom Eye will be saved into the demo folder.

```bash
python ZoomEye/demo.py \
    --model-path lmms-lab/llava-onevision-qwen2-7b-ov \
    --input_image demo/demo.jpg \
    --question "What is the color of the soda can?"
```

### 2. Run the Gradio Demo

We also provide a Gradio Demo. Run the script and open `http://127.0.0.1:7860/` in your browser.

```bash
python gdemo_gradio.py
```
