        # Visiblity Graph Analysis Overview

This code performs a simple [visiblity graph analysis](https://en.wikipedia.org/wiki/Visibility_graph_analysis). The further to the right on the colormap below, the more visible the point.

## Examples

### Four-way intersection

- **Input:** `test_imgs/four_in.png`

- **Output:** `test_imgs/four_out.png`

| Input Image | Output Image |

|-------------|--------------|

|  |  |

### Rectangles

- **Input:** `test_imgs/rectangles_in.png`

- **Output:** `test_imgs/rectangles_out.png`

| Input Image | Output Image |

|-------------|--------------|

|  |  |

### Floor Plan

- **Input:** `test_imgs/floorplan_in.png`

- **Output:** `test_imgs/floorplan_out.png`

| Input Image | Output Image |

|-------------|--------------|

### Streets (using coordinates)

- Coordinate Input: 40.7611, -73.6533 | 40.7490, -73.6773 | (shown in `test_imgs/streets_in.png`)

- **Output:** `test_imgs/streets_out.png`

| Input | Output Image |

|-------------|--------------|

|  |  |

## Usage

To use the code, simply run `run.py`. 

I recommend [Open Street Map](https://www.openstreetmap.org/export) for finding coordinates, but you can use whatever you prefer.
