The OCR Tool reads printed text and translates it to ASCII text. This tool:
Reads multiple lines of text in a single ROI (region of interest).
Features pre-loaded OCR fonts that are designed to be read without the need for training.
Features user-trained fonts for more robust character recognition.
Uses a multi-neural network model to allow greater character variation.
Features Image Pre-Processing, which makes it easier for the tool to recognize and read characters in an image.
The OCR Tool has a Standard OCR capability and an IntelliText OCR capability. Select Standard OCR or IntelliText OCR from the dropdown menu above the tool parameters.
Standard OCR is sufficient for most applications, and offers font selection and editing, the ability to create new fonts, user-definable text reading confidence, auto-sizing or character selection based on width, height, and connection strength, and match string functionality.
IntelliText OCR offers most features of the standard algorithm plus the ability to set character polarity, use regular expression syntax in Match String, and perform image binarization. Use IntelliText OCR for symbols that are badly printed or marked. The IntelliText OCR algorithm is optimized for identification of characters that are tilted, out of scale, badly segmented, or otherwise difficult to read with the standard algorithm.
Important: When switching between Standard OCR and IntelliText OCR, the links between tool outputs and GDS tags are lost. This is because the underlying components that make up the OCR Tool are completely removed and then recreated whenever you change the tool’s capability.
