This repository contains the pre-trained neural loss recovery module checkpoints for the **ReVo** system. These models are designed to perform neural loss recovery for volumetric videoconferencing systems, recovering lost packets across different video codecs.

## Model Details

The repository includes 6 distinct models, organized by the compression codec and the RGB and Depth modality.

**Supported Codecs:**
* `h264` (Advanced Video Coding)
* `h265` (High Efficiency Video Coding / HEVC)
* `dcvcrt` (Deep Contextual Video Compression)

# How to Use?

```python
from huggingface_hub import hf_hub_download
import torch

# Define the specific codec and modality you want to load
codec = "h265"      # Options: 'h264', 'h265', 'dcvcrt'
modality = "depth"  # Options: 'rgb', 'depth'

# Download the specific checkpoint
checkpoint_path = hf_hub_download(
    repo_id="umass-lass/ReVo", 
    filename=f"{codec}/{codec}_{modality}.pth"
)

# Load the weights into your PyTorch model
# model.load_state_dict(torch.load(checkpoint_path))
print(f"Successfully downloaded to: {checkpoint_path}")
```
