Color-matching systems test visual quality
Color is a human perception based on a number of factors, and it is one of the most important visual cues we have for inspecting objects. For example, to make sure a consumer product elicits the desired color perception from the purchaser or user, manufacturers must test it under standardized conditions with a system that mimics human vision.
There are many ways to use color in machine vision, but one application is ensuring that every part of a product visually matches and that products displayed next to one another match. Mis-colored packaging, for example, may cause customers to think a product is old or defective in comparison to the surrounding correctly colored packages. These types of perceptions can be predicted, quantified, and corrected by carefully installing a visual color-matching system.
