Visiblity Graph Analysis Overview

This code performs a simple visiblity 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

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 for finding coordinates, but you can use whatever you prefer.
