Optical character recognition (OCR) is a vital tool for the food and pharmaceutical industries, allowing them to inspect for correct labelling and thereby conforming to good manufacturing practices (GMP).

Outlines some of the areas in machine vision system solution which have seen the most significant advances as a result of technology enhancement and particularly the rapid development in semiconductor technology. Looks at the background of machine vision development and improvements brought about by modern technology, covering advances in vision algorithms, “warp engines” used in combination with an application specific integrated circuit [ASIC], improvements in human interface; and optical character recognition. Concludes that the trend now is for general purpose vision processing systems to provide greater capability, at greater throughput speed, without significantly increasing the cost of the system which means that they are now part of the original process design to inspect critical stages of manufacture.

Clive Loughlin looks at some of the systems available to industry, and analyses their strengths and weaknesses.
