Industrial Machine Vision

& Image Processing Course


1. Course Objectives

This course aims to give participants a good foundation in image processing theory as well as the ability to apply this knowledge to the design and implementation of systems for machine vision in the real world. Components of machine vision systems that are currently available in the market will be discussed. There will also be hands-on sessions to perform simple machine vision tasks on an integrated system. The course will also touch on the trends evident in the machine vision industry with the advent of technological advances in processing power and higher transistor density.
