Image analysis for product quality

This article is brought to you by: 

Image analysis and machine vision have a common goal of extracting information from digital images. They differ mostly in what objects or parts they are applied to and the type of information extracted. Both use image processing - computations that modify an input image to make image elements more obvious. As examples, image processing is used to compensate for variations in lighting and to enhance the edges of objects. Machine vision is primarily concerned with locating, identifying, measuring and inspecting manufactured parts such as fasteners (bolts, screws, etc.). Image analysis is primarily concerned with measuring natural or non-manufactured parts and patterns. Applications include classifying and counting biological cells and characterising particles, textures or foams.
