Segmentation & Count
OTSU Dark... - OTSU is a method to determine the threshold of an adaptive based on the gradation charac -
teristic of an image, then divide the image into the background and the targets of interest. The larger the
difference between the background and the target, the large a difference is displayed between the two, while
the smaller differences will be less displayed. Specifically, the dark method means the segment from the dark
objects from the bright objects are determined using an OTSU algorithm, and is best used with a dark target
object with a bright background. This method is best when you need accuracy, as it minimizes possibility for
misclassification and missegmentation.
A pproximation - Assigns whether the segments will be estimated as circles, ellipses, or none (the actual shape
and size of the segment).
With Holes - This tick box enables the segmentation method to create holes within a segment for areas that do
not fit the segment.
Outline Style - Assigns whether the segments will be colored in, outlined, or none (simply numbered).
Outline Color - Assigns which color the segments or outlines will be colored in.
Label Method - Assigns how the segments will be labeled. XOR contrasts the numbers against the background,
true allows a color to be selected for all, and false eliminates numbering the sections entirely.
Label Color - When true is selected as the “Label Method,” will allow selection of the color to use for the num -
bering.
Label Type - When true is selected as the “Label Method,” allows selection between displaying counted seg -
ments, the area of each segment, or the perimeter of each segment.
