Concave hull algorithms with pseudo code
- Moreira, A. and Santos, M.Y., 2007, Concave Hull: A K-nearest neighbors approach for the computation of the region occupied by a set of points PDF
- python implementation: https://github.com/sebastianbeyer/concavehull
- blog discussion + reference to python implementation https://towardsdatascience.com/the-concave-hull-c649795c0f0f
- Duckham, Matt, et al. "Efficient generation of simple polygons for characterizing the shape of a set of points in the plane." Pattern recognition 41.10 (2008): 3224-3236. PDF
The k-NN approach seems simpler to implement.
- also interesting (at least for testing) but a bit heavy as dependency "Toolbox for generating n-dimensional alpha shapes." https://github.com/bellockk/alphashape
