# 🧠 Open Humanoid Actuated Face Dataset

</p>

## Dataset Summary
The **Open Humanoid Actuated Face Dataset** is designed for researchers working on  
facial‑actuation control, robotics, reinforcement learning, and human–computer interaction.

* **Origin** – collected during a reinforcement‑learning (RL) training loop whose objective was to reproduce human facial expressions.
* **Platform** – a modified **i2Head InMoov** humanoid head with a silicone skin.
* **Control** – **16 actuators** driving facial features and eyeballs.
* **Pairing** – each example contains the raw RGB image **and** the exact actuator angles that produced it.

## Dataset Structure

| Field           | Type          | Description                                                   |
|-----------------|---------------|---------------------------------------------------------------|
| `image`         | `Image`       | RGB capture of the humanoid face (resolution **[FILL_RES]**). |
| `actuated_angle`| `struct`      | 16 integer values (`"0"`, `"1"` .. so on)  |

## Dataset Statistics

| Split | Samples | Size |
|-------|---------|------|
| **Train (full)**  | **[FILL_TOTAL]** | ≈ 105 GB |
| **Train (small)** | 2 | ≈ 2 GB |

*(Numbers shown are for the preview release — update as you add data.)*

## Usage Example

```python
from datasets import load_dataset, Image

# load the small subset
ds = load_dataset("iamirulofficial/OpenHumnoidDataset", name="small", split="train")
ds = ds.cast_column("image", Image())   # decode image bytes ➜ PIL.Image

img = ds[0]["image"]
angles = ds[0]["actuated_angle"]        # {'0': 90, '1': 20, ...}
img.show()
print(angles)
````

> **Tip** 
> For the full corpus use `name="full"` (may require `streaming=True` once the dataset grows).

## Data Collection & RL Setup

A detailed description of the RL pipeline, reward design, and actuator hardware will appear in our upcoming paper (in preparation, 2025). Briefly:

1. **Vision module** extracts target expression keypoints from live human video.
2. **Policy network** predicts 16 actuator set‑points.
3. **Real‑time reward** computes expression similarity + smoothness penalties.
4. Images & angle vectors are logged every *N* steps, forming this dataset.
