healpix_analyse#

Signal-analysis and spatial-analysis tools for HEALPix data.

The package contains operators for:

  • multi-resolution HEALPix processing,

  • spherical-harmonic analysis,

  • local FFT analysis,

  • Minkowski functionals,

  • physical-radius neighbourhood reductions,

  • connected-component analysis on HEALPix topology.
