-- TRAJECTORY SHAPE MATCHING --

! To test the program, simply run shape_matching_final.py from command line
with number 1-3 as an argument. If no argument is given, program uses matchShapes
function version 1, which actually gives the best results. !

Route drawing:

- route images are already generated from .txt files in 'sample_trajectories' folder
- route_drawing.py can be used to generate more images
	- add new routes in sample_trajectories folder as .txt files
	- run route_drawing.py with file name (without .txt) as command line argument
	-	 e.g. 'python3 route_drawing.py route1'

Shape matching:

- shape_matching.py goes through all the route images
in 'routes' folder and compares them to every sample image in 'samples'
	- user needs to press any button to iterate through the comparisons
	- final results are printed to command line

- there is also possibility for rotating routes but it is not used
since opencv matchShapes function is rotation invariant

- note that by default route images are dilated a little bit
to make the contours smoother and easier to compare
