Detailed Description
A SpinImageCustom descriptor computes a spin image spinning around a custom reference direction/axis.
The custom axis is the "beta" axis as described in Johnson & Hebert 1999.
Example spin image definition with 3 rows and 4 cols:
beta
^
|_ _ _ _
|_|_|_|_|
x_|_|_|_|
|_|_|_|_|
-----------> alpha
(x = center point of spin image, beta = [custom reference direction]
The center point of the spin image is the given interest point or the centroid of given regions of interest points

Instantiates the spin image descriptor to use the given specifications.
- Warning:
- The number of rows (nbr_rows) must be odd
- Parameters:
-
ref_x The x dimension of the beta vector ref_y The y dimension of the beta vector ref_z The z dimension of the beta vector row_res The cell resolution along the beta axis col_res The cell resolution along the alpha axis nbr_rows The number of cells along the beta axis nbr_cols The number of cells along the alpha axis use_interest_regions_only When computing for interest regions, true indicates to use only the points within the interest region to compute the spin image
