# Matching shapes
2+
This python script shows the degree of matching of shapes.
3+
4+
## Setup Instructions
5+
### Install python3
6+
sudo apt-get install python3
7+
### Install pip (package installer for python)
8+
sudo apt-get install python3-pip

11+
### Install tkinter library
12+
sudo apt-get install python3-tk
13+
14+
## Details/Output
15+
A dialog box appears with option to select images 1 and 2. Then clicking proceed will display the degree of similarity of the shapes in the two selected images.
