image pixels to black. Pixels inside the threshold interval are considered
part of the particle region. Pixels outside the threshold interval are
considered part of the background region.
Inverse binarization reverses the assigned bit numbers of the particle region
and the background region. All pixels that belong in the threshold interval,
or the particle region, are set to black, and all pixels outside the threshold
interval, or the background region, are set to the image white value.
Figure 3-5 illustrates binarization and inverse binarization.

You can enable hardware binarization in the following ways:
• In Vision Builder AI, configure the Lookup Table attribute on the
Advanced tab of the Acquire Image (Smart Camera) step. Refer to
the NI Vision Builder for Automated Inspection: Configuration Help
for more information.
• In MAX, use the Lookup Table drop-down box on the LUT tab of the
smart camera configuration page to enable hardware binarization.
Refer to the Measurement & Automation Explorer Help for NI-IMAQ
