sh2power

Synopsis

Compute the total power of a spherical harmonics image

Usage

sh2power [ options ]  SH power
  • SH: the input spherical harmonics coefficients image.
  • power: the output power image.

Description

This command computes the sum of squared SH coefficients, which equals the mean-squared amplitude of the spherical function it represents.

Options

  • -spectrum output the power spectrum, i.e., the power contained within each harmonic degree (l=0, 2, 4, ...) as a 4-D image.

Standard options

  • -info display information messages.
  • -quiet do not display information messages or progress status.
  • -debug display debugging messages.
  • -force force overwrite of output files. Caution: Using the same file as input and output might cause unexpected behaviour.
  • -nthreads number use this number of threads in multi-threaded applications (set to 0 to disable multi-threading)
  • -failonwarn terminate program if a warning is produced
  • -help display this information page and exit.
