# CV Lab Camera

CV Lab Camera is a Gradio application and developer suite for computer vision, scientific image analysis, geometric transformations, morphology, neural style transfer, AR face overlays, and batch dataset processing.

---

## Developer Quickstart

### 1. Web App
Launch the interactive Gradio laboratory:
```bash
python app.py
```

### 2. Command Line Interface (CLI)
Process images directly from your terminal or shell scripts:
```bash
# Apply built-in filter
python cli.py filter --input input.jpg --filter Sepia --output result.jpg

# Apply geometric transformation
python cli.py transform --input input.jpg --op Rotation --angle 45 --output result.jpg

# Apply morphological operation
python cli.py morph --input input.jpg --op Opening --size 5 --output result.jpg

# Apply AR face overlay
python cli.py ar --input face.jpg --filter Glasses --output ar_result.jpg

# Apply neural style transfer
python cli.py style --input content.jpg --style-image style.jpg --output stylized.jpg

# Batch process dataset
python cli.py batch --dir ./my_dataset --filter Grayscale --output-zip processed.zip
```

### 3. Python Developer SDK (`developer_api.py`)
Import CV Lab functions directly in your Python code:
```python
from developer_api import process_image, generate_python_snippet

# Process image programmatically
result, meta = process_image(
    image_input="photo.png",
    operation_type="filter",
    operation_name="Sepia",
    output_path="output_sepia.png"
)

# Generate copy-pasteable Python code
code = generate_python_snippet("Sepia", {"contrast": 1.2})
print(code)
```

## Custom Filters & AR Filters

### Image Processing Filter Pipelines
Save multi-step filter pipelines as JSON:
```json
[
  {"operation": "Grayscale", "params": {}},
  {"operation": "Sharpen", "params": {"amount": 1.4}}
]
```

### Custom AR Face Filters
Design landmark-based AR overlays attached to `head_top`, `forehead`, `eyes`, `nose`, `mouth`, `chin`:
```json
{
  "elements": [
    {
      "landmark": "forehead",
      "shape": "crown",
      "color": [255, 215, 0],
      "scale": 1.0,
      "offset_y": -0.15
    },
    {
      "landmark": "eyes",
      "shape": "visor",
      "color": [0, 255, 255],
      "scale": 1.0
    }
  ]
}
```
