DESCRIPTION

You can view the birth and death pixels s for 2D cubical filtrations of persistence digrams interactively. You can use the diagrams created by pict.binarize or pict.pixel_levelset, and dipha.

If you want to use this program, you need to run pict.binarize or pict.pixel_levelset with -i/-I option and create index_map.
