info_parallels_xld — 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, see gen_parallels_xld for the corresponding calculation), 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.
