In the Segmentation part, select segmentation method and blob type.
Segmentation is the division of the pixels in an image into object pixels and
background pixels. Typically objects are assigned a value of 1 while
background pixels are assigned a value of 0.
Static method uses gray values to divide blob pixels and background pixels.
All pixels with a grayscale value below the threshold are assigned as object
pixels, while all pixels with values above the threshold are assigned as
background pixels.
Relative method uses a relative threshold expressed as the percentages of
the total pixels between the left and right tail to divide blob pixels and
background pixels. Tails represent noise-level pixels that lie at the extremes
of the histogram (the lowest and the highest values).
