Acknowledgements

perch builds upon the work of several excellent open-source projects:

Cubical Ripser (cripser)

perch uses cripser for fast persistent homology computation on cubical complexes. We gratefully acknowledge the developers of Cubical Ripser for creating this efficient implementation that makes perch’s analysis possible. If you use perch in published work, please also cite the Cubical Ripser paper: Kaji, S., Sudo, T., & Ahara, K. (2020), Cubical Ripser: Software for computing persistent homology of image and volume data (arXiv:2005.12692).

Connected Components 3D (cc3d)

Structure segmentation in perch relies on cc3d for fast connected component labeling. We thank the developers for this high-performance library.

astrodendro

The hierarchical structure analysis in perch was inspired by astrodendro, a dendrogram-based structure identification package for astronomical data. We acknowledge the astrodendro developers for their work on hierarchical structure analysis in astronomy and influencing perch’s design.
