TECHNICAL NOTE
When designing a machine vision system, it is important to enhance the contrast of the inspected object’s
features of interest. Filtering provides a simple way to enhance the contrast of the image while blocking
out unwanted illumination. There are many di erent ways lters can enhance contrast, and the lter type is
dependent on the application. Some common lters used in machine vision are colored glass, interference,
Neutral Density (ND), and polarization.

used to lter out cool colors on the opposite side of the wheel.
