Description

identify the orientations of the N largest peaks of a SH profile

syntax:     find_SH_peaks [ options ] SH directions ouput

Arguments

SH the input image of SH coefficients.
directions the set of directions to use as seeds for the peak finding
ouput the output image. Each volume corresponds to the x, y & z component of each peak direction vector in turn.

Options

-num peaks the number of peaks to extract (default is 3).
peaks the number of peaks
-direction phi theta the direction of a peak to estimate. The algorithm will attempt to find the same number of peaks as have been specified using this option.
phi the azimuthal angle of the direction (in degrees).
theta the elevation angle of the direction (in degrees, from the vertical z-axis).
-peaks image the program will try to find the peaks that most closely match those in the image provided.
image an image containing the true peaks to be estimated.
-threshold value only peak amplitudes greater than the threshold will be considered.
value the threshold value
