Introducing machine vision

A machine vision is a machine with camera capabilities and an understanding of what objects are. The machine uses its camera to sense physical objects around its environment. Machine vision or computer vision is a field where a machine acquires, analyzes, and understands a still image or video. This field involves knowledge such as image processing, pattern recognition, and machine learning.

The pattern recognition and machine learning fields helps us to teach our machine to understand images. For instance, when we show a still image with people inside a car to the machine, then the machine should identify which are the people. Furthermore, in some cases, the machine also should guess the person in an image. From a pattern recognition and machine learning view, we should register the person so the machine can know the person in the image after identifying the person in an existing image.

To build a machine vision, we use the general design that is shown in the following...
