info_para_xld ( Parallels, Image : : : QualityMin, QualityMax, GreyMin, GreyMax, StandardMin, StandardMax )
Return information on the gray values of the area enclosed by XLD parallels.
info_para_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_para_xld. The operator returns
ranges for the quality factor (QualityMin and
QualityMax), the mean gray value (GreyMin and
GreyMax), and the standard deviation with respect to the
mean gray value (StandardMin and StandardMax).
This operator serves to determine appropriate thresholds for
mod_para_xld.
