To identify characters in an image, the LabVIEW software needs to be trained to identify each character. The optical character recognition (OCR) function using Vision Assistant offers an excellent procedure to train the software to recognize the imaged characters. This chapter talks about an OCR VI, which performs real‐time character identification. It demonstrates the use of OCR function to identify characters from an imaged printed paper. To use the OCR function, a character set file having trained character information is required. The chapter shows the character identification results when the main VI is executed. To identify characters in the image display, a ROI is placed around the character set to be identified.
