README

The script is called occupancy.py

You do not need to edit the script. Prepare a text file in which
the first line is the radius of the area of influence.

After the first line, each line has one pair of x,y coordinates separated by a comma. 
An example file is provided called coords.txt

The units are the same for the radius and for the coordinates.
For example pixels or mm. It does not matter how the coordinates have been 
generated.

The occupancy area computed is the area of all regions of influence
taking into account the overlap. This value is written in the output and
also saved in a file called result.txt. In the file the first column is 
a timestamp, the second is the occupancy area.

The program has been tested on a Mac, not on Windows.
For copyright and reference see the top of the script.

Known issues:
Remove any blank lines at the end of your text file.
For number of elements above 50 the program is slow and 
exponentially more so as the number increases.
