Compute the total power of a spherical harmonics image
sh2power [ options ] SH power
- SH: the input spherical harmonics coefficients image.
- power: the output power image.
This command computes the sum of squared SH coefficients, which equals the mean-squared amplitude of the spherical function it represents.
- -spectrum output the power spectrum, i.e., the power contained within each harmonic degree (l=0, 2, 4, ...) as a 4-D image.
- -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.
- -version display version information and exit.
