The module aal.py contains a simple and illustrative implementation of the method presented in the paper Rotation Invariant Distance Measures for Trajectories (2004), by Michail Vlachos et al., to convert a sequence of points in the XY space to another sequence of points in the Angle-Arc-Length (AAL) space.
First, I recommend that you create a virtual environment, so that you don't pollute your global space. If you're using PyCharm, see their documentation on how to create it directly from the IDE.
Now, you can install this package with the following command
pip install -e .
You can omit -e if you don't need or want to see the effect of the changes that you make.
I've prepared 2 examples that illustrate the implemented method. You can find them inside the folder examples.
To execute one of them, run the corresponding module
python examples/example1.py
or
python examples/example2.py
If you get an error related to Qt or PyQt, you might need to install Qt first, because that's the backend that is being used by matplotlib in these examples. Alternatively, you can change the backend that matplotlib uses.
