persim.bottleneck_matching

persim.bottleneck_matching(I1, I2, matchidx, D, labels=['dgm1', 'dgm2'], ax=None)[source]

Visualize bottleneck matching between two diagrams

Parameters
  • I1 (array) – A diagram

  • I2 (array) – A diagram

  • matchidx (tuples of matched indices) – if input matching=True, then return matching

  • D (array) – cross-similarity matrix

  • labels (list of strings) – names of diagrams for legend. Default = [“dgm1”, “dgm2”],

  • ax (matplotlib Axis object) – For plotting on a particular axis.

Examples

bn_matching, (matchidx, D) = persim.bottleneck(A_h1, B_h1, matching=True) persim.bottleneck_matching(A_h1, B_h1, matchidx, D)
