OCR is widely accessible today and continues to increase efficiency for personal and professional purposes.ĭata scientists will distinguish different types of OCR software depending on their application and use. With that, there was a higher chance of errors in the content. Before this software was available, documents had to be manually retyped - taking much more time, effort, and resources. Document processing workflows are able to be automated through advanced methods of OCR. Today, OCR has the capability to give users nearly perfect accurate conversions. OCR has seen several developments since this time. This technology was not popularized until the early 1990s, when it was being used to digitize historical newspapers. He sold his company to Xerox in 1980, as Xerox was interested in continuing to commercialize paper-to-computer text transformation. He made a reading machine that was able to read text out loud and translate text into a text-to-speech format. Kurzweil determined that the best use for his technology would be a machine learning device for those who are blind. This new technology could recognize text that was printed in just about any font. This document-transforming technology was developed in 1974 by Ray Kurzweil, who started Kurzweil Computer Products, Inc. When OCR doesn’t recognize text, be sure to check that your scan is high quality, with plenty of light, and that the scan is not skewed. Some OCR software can make annotated PDFs that have before and after versions of a scanned document. Post processing - After the content is analyzed, the system changes the extracted text data to be a computerized file. This method works best with images that are scanned from documents that have been typed in a font that is already known.Ĥ. Pattern recognition can only operate when the glyph that is stored has a similar scale and font to the glyph that is added. Pattern matching is when a character image, called a glyph, is isolated and compared to a similar glyph that is already stored. ![]() From there, it uses these components to search for the best match or its closest one.
