QUESTION

Python Ripser Get Vertices for Diagram Point

Asked 2021-Sep-02 at 05:06

I am using the Python package ripser for persistence homology. I would like to leverage this to aide in segmenting 2D point clouds.

As an example, I am following Elizabeth Munch: Python Tutorial on Topological Data Analysis. Here, I take the DoubleAnnulus and increase the separation between the two:

...

K-means clustering would work nicely here (our data is fairly convex and the algorithm doesn't require labels). Since key features on persistence graphs have a large y-distance from the line y = x, we can generate a histogram of the 1-dim Diagram y-distances from the line y = x and use the number of points more than 3 standard deviations above the mean as our k-value.
