# Visual Spatial Intelligence Benchmark (VSI-Bench)
This repository contains the visual spatial intelligence benchmark (VSI-Bench), introduced in [Thinking in Space: How Multimodal Large Language Models See, Remember and Recall Spaces](https://arxiv.org/pdf/). 


## Files
The `test-00000-of-00001.parquet` contains the full dataset annotations and images pre-loaded for processing with HF Datasets. It can be loaded as follows:

<!-- @shusheng -->
```python
from datasets import load_dataset
vsi_bench = load_dataset("nyu-visionx/VSI-Bench")
```

Additionally, we provide the compressed raw videos in `*.zip`.


## Dataset Description
VSI-Bench quantitatively evaluate the visual-spatial intelligence of MLLMs from egocentric video. VSI-Bench comprises over 5,000 question-answer pairs derived from 288 real videos. These videos are sourced from the validation sets of the public indoor 3D scene reconstruction datasets `ScanNet`, `ScanNet++`, and `ARKitScenes` and represent diverse environments -- including residential spaces, professional settings (e.g., offices, labs), and industrial spaces (e.g., factories) and multiple geographic regions. Repurposing these existing 3D reconstruction and understanding datasets offers accurate object-level annotations which we use in question generation and could enable future study into the connection between MLLMs and 3D reconstruction.

The dataset contains the following fields:

| Field Name | Description |
| :--------- | :---------- |
| `idx` | Global index of the entry in the dataset |
| `dataset` | Video source: `scannet`, `arkitscenes` or `scannetpp` |
| `question_type` | The type of task for question |
| `question` | Question asked about the video |
| `options` | Answer choices for the question (only for multiple choice questions) |
| `ground_truth` | Correct answer to the question |
| `video_suffix` | Suffix of the video  |

### Example Code

<!-- @shusheng -->
```python
import pandas as pd
# Load the CSV file into a DataFrame
df = pd.read_csv('cv_bench_results.csv')
# Define a function to calculate accuracy for a given source
def calculate_accuracy(df, source):
    source_df = df[df['source'] == source]
    accuracy = source_df['result'].mean()  # Assuming 'result' is 1 for correct and 0 for incorrect
    return accuracy
# Calculate accuracy for each source
accuracy_2d_ade = calculate_accuracy(df, 'ADE20K')
accuracy_2d_coco = calculate_accuracy(df, 'COCO')
accuracy_3d_omni = calculate_accuracy(df, 'Omni3D')
# Calculate the accuracy for each type
accuracy_2d = (accuracy_2d_ade + accuracy_2d_coco) / 2
accuracy_3d = accuracy_3d_omni
# Compute the combined accuracy as specified
combined_accuracy = (accuracy_2d + accuracy_3d) / 2
# Print the results
print(f"CV-Bench Accuracy: {combined_accuracy:.4f}")
print()
print(f"Type Accuracies:")
print(f"2D Accuracy: {accuracy_2d:.4f}")
print(f"3D Accuracy: {accuracy_3d:.4f}")
print()
print(f"Source Accuracies:")
print(f"ADE20K Accuracy: {accuracy_2d_ade:.4f}")
print(f"COCO Accuracy: {accuracy_2d_coco:.4f}")
print(f"Omni3D Accuracy: {accuracy_3d_omni:.4f}")
```
