Description

SPM: computes the number of resels in a volume - a compiled routine

Usage

1
R = spm_resels_vol(V,W)

Arguments

V

a memory mapped image volume. Finite and non-zero values are considered to be part of the search volume.

W

smoothness of the component fields FWHM in voxels.

Value

Resel counts, where: R(1) - Euler Characteristic of the volume (number of connected components - number of holes). R(2) - Resel Diameter (average over all rotations of the distance between two parallel planes tangent to the volume in resel space). R(3) - Resel Surface Area (half the surface area of the volume in resel space). R(4) - Resel Volume (the volume in resel space).
