# Equalize

The Equalize operator remaps the pixels in the image so that successive acquired images have similar grey values.

Use an equalize operation when the lighting in your production environment can vary slightly from one image to the next, or when some aspect of the objects you are inspecting, such as color, are allowed to vary slightly. The equalize operation helps to ensure that irrelevant changes in your production environment do not impact the overall result of the vision application.
