Official repository for the  **FRED dataset**, a large-scale multimodal dataset specifically designed for drone detection, tracking, and trajectory forecasting, with spatiotemprally  **synchronized RGB and event data**.
It includes **train** and **test** splits with zipped subfolders for each sequence.

The dataset can also be **downloaded** from [here](https://drive.google.com/drive/folders/1pISIErXOx76xmCqkwhS3-azWOMlTKZMp?usp=share_link).
The dataset splits in .txt format, along with the alternative **challenging split**, can be found [here](https://github.com/miccunifi/FRED/tree/main/dataset_splits).

**Demos and examples** can be found in the official [website](https://miccunifi.github.io/FRED/). Check it out, it's pretty cool! :)

## 📂 Dataset Structure

```
FRED/
 ├── train/
 │    ├── 0.zip
 │    ├── 1.zip
 │    └── ...
 ├── test/
 │    ├── 100.zip
 │    ├── 101.zip
 │    └── ...
```

Each `.zip` file corresponds to one sequence (rgb frames, event data, and annotations).
Event data comprends both already extracted event frames and the relative **.hdf5 file**, containing the raw event stream.

---

## 📝 Annotation Format

Each sequence includes two **`.txt` annotation file** with bounding box and identity information for every frame.  
Since rgb images are padded to enable a same coordinate space between the two modalities, the event videos have additional boxes corresponding to the padded area in the RGB.
To better divide the 2 cases, we divided the annotation into **`coordinates.txt`** that represents the **extended boxes** and the **`coordinates_rgb.txt`** for the boxes **excluding the padding**.

We reccomend using the **extended boxes** version since it facilitates the training and the overall cases in which the drone falls into the padding is relatively limited when compared to the number of samples.

The format of the annotations is:

```
time: x1, y1, x2, y2, id, class
```
- **time**  → time relative to the start of the recording in 'seconds.microseconds' for the annotation
- **x1, y1** → top-left corner of the bounding box  
- **x2, y2** → bottom-right corner of the bounding box  
- **id** → unique identifier for the drone, consistent across frames (for tracking)  
- **class** → drone type label  

📌 Example:
```
1.33332: 490.0, 413.0, 539.0, 448.0, 1, DJI Mini 2
6.33327: 609.0, 280.0, 651.0, 308.0, 2, DarwinFPV cineape20 
```

This structure is compatible with standard detection and tracking pipelines, while maintaining instance-level identity across time.
