# Photo Background Remover

A simple Go program that captures a photo from your webcam and removes the background.

## Prerequisites

### 1. Install ffmpeg
```bash
# Ubuntu/Debian
sudo apt install ffmpeg

# macOS
brew install ffmpeg
```

### 2. Install Docker
```bash
# Ubuntu/Debian
sudo apt install docker.io

# macOS
brew install --cask docker
```

The program uses the `danielgatis/rembg` Docker container for background removal. The AI model (~176MB) will be downloaded automatically on first run.

## Usage

1. Build and run the program:
```bash
go run main.go
```

2. The program will:
   - Capture a photo from your webcam
   - Remove the background
   - Save both images in the `output/` directory

## Output

- `output/photo_TIMESTAMP.jpg` - Original photo
- `output/photo_TIMESTAMP_nobg.png` - Photo with background removed

## Troubleshooting

- **Webcam not found**: Make sure `/dev/video0` exists (Linux) or adjust the device in the code
- **ffmpeg not found**: Install ffmpeg using the commands above
- **Docker not found**: Install Docker using the commands above
- **Docker permission denied**: Add your user to the docker group: `sudo usermod -a -G docker $USER` (then log out and back in)
- **Webcam permission denied**: You may need to add your user to the `video` group: `sudo usermod -a -G video $USER`
