If the textures of interest are larger than a few pixels, we recommend
you subsample the image with a factor <1 to speed up the processing.
Downsampling the image will let you detect larger structures with a
smaller sized structure element. A factor >1 might increase the accuracy
but also require more processing time. Images are typically of higher
resolution than is required for granularity measurements, so the default
value is 0.25. For low-resolution images, increase the subsampling
fraction; for high-resolution images, decrease the subsampling fraction.
Subsampling by 1/4 reduces computation time by (1/4) :sup:`3` because the
size of the image is (1/4) :sup:`2` of original and the range of granular
spectrum can be 1/4 of original. Moreover, the results are sometimes
actually a little better with subsampling, which is probably because
with subsampling the individual granular spectrum components can be used
as features, whereas without subsampling a feature should be a sum of
several adjacent granular spectrum components. The recommendation on the
numerical value cannot be determined in advance; an analysis as in this
reference may be required before running the whole set. See this `pdf`_,
slides 27-31, 49-50.

It is important to remove low frequency image background variations as

simply subtract a highly open image. To do it quickly, we subsample the
image first. The subsampling factor for background reduction is usually
[0.125 – 0.25]. This is highly empirical, but a small factor should be

background removal in the context of granulometry is that image volume
