Detailed Description

Machine vision modules implement machine vision functionalities for end users, and can be selected at runtime simply by changing the video resolution, pixel format, and framerate on some video capture software running on a host computer.

Modules may include a hierarchy of sub-components that each implements a particular machine vision algorithm.
