Main Options

Radius of spheres to detect in physical length units (typically mm). [Default: 1]
Half of filter margin width in pixels. This determines the extent of the region around the surface or the sphere where the detection filter is non-zero. [Default: 2]
Use intensity-normalized filter, effectively computing Normalized Cross Correlation between filter and image.
