Return information about the gray values of the area enclosed by XLD
parallels.
::info_parallels_xld calculates various gray value
features of the area enclosed by the XLD parallels
Parallels. The input image Image is used to
get the gray values needed for this. The algorithm used in this
operator is very similar to the one used in
::mod_parallels_xld. The operator returns ranges for the
quality factor (QualityMin and QualityMax),
the mean gray value (GrayMin and GrayMax), and
the standard deviation with respect to the mean gray value
(StandardMin and StandardMax).
This operator serves to determine appropriate thresholds for
::mod_parallels_xld.
