The two HSL modes let you specify H, S, and L values for both Color and Tolerance. These can
be set numerically, using values from 0 to 255, or in a color or greyscale window, by adjust-
ing the size and location of a selection box.
Color:
l Hue determines the colors to be considered. This is depicted and con-
trolled by the horizontal location of the selection box within the color
selection window.
l
Saturation determines the intensity of the hues to be considered. This is
depicted and controlled by the vertical location of the selection box
within the color selection window.
l Luminance (or Lightness) sets the brightness of the colors that appear
within the color selection window. Increasing luminance is like adding
white to a color.
Tolerance:
l Tolerance values are distributed equally above and below the color range
to which they apply. A larger tolerance value will include a larger number
of colors.
l
Hue tolerance determines how wide a range of colors will be considered.
This is depicted and controlled by the width of the selection box.
l
Saturation tolerance determines the range of intensity of colors to be
considered. This is depicted and controlled by the height of the selection
box.
l Luminance (or Lightness) tolerance determines the range of brightness
to be considered for valid blobs. This is depicted and controlled by the
width of the selection box in a grey scale selection window below the
color selection window.
HSL Inside
The HSL Inside mode sets an HSL range that specifies what colors can be con-
tained in a valid blob.
HSL Outside
The HSL Outside mode sets an HSL range that specifies what colors cannot be
contained in a valid blob.
Configuring Thresholds
Threshold functions set values at which image segmentation takes place. Depending on the
segmentation mode selected, there may be either a single threshold or a double threshold.
