Optical character recognition technology overcomes limitations

Cognex Corporation (www.cognex.com) has introduced OCRMax™, a new tool for optical character recognition (OCR) and verification (OCV) applications that gives Cognex vision systems and vision software the power to achieve high read rates while keeping misreads to a minimum. OCRMax is an all-in-one tool that can handle character variations, text skew, proportional fonts and variable string lengths. It is easy to set up and simple to use, with little training required. The key to achieving the highest read rates with OCRMax is its character segmentation capability. The segmenting functionality takes each character line and splits it into individual regions that each contain one character. This functionality ensures that OCRMax can handle distorted, touching and variably spaced characters and can also accommodate uneven surfaces and lighting variations on the production line. Also, OCRMax lets users control key parameters to further improve segmentation performance, resulting in even higher read rates and fewer misreads.
