That’s why even though PDFs look like regular text documents, computers can’t always copy text from them.
The text in a PDF is part of the image itself, rather than distinct pieces of information readable by a computer.
can help digitize all kinds of documents for your convenience.
OCR makes it possible for you to keep all the important papers and documents you collect as a person or a business without requiring the physical space to store them all.
For instance, in the image below the respondent filled in a bubble to indicate that they are in the age group of 31 to 45.
In addition to multiple choice kinds of data, OMR can be used to capture names, ID numbers, and other non-multiple choice data as illustrated below.The black areas will be recognized as potential text while the white background is ignored, further increasing the OCR software's accuracy.While some legacy OCR solutions only uses one pass to extract text information from an image, almost all modern OCR software uses two passes.There are two types of algorithms that OCR software can use to recognize text within an image: Once the image has been created, there are still steps that need to be taken before OCR software can begin parsing text from it.Broadly speaking, there are three basic steps to the OCR process: pre-processing, first pass and second pass.During the second scan, or second pass, OCR software begins analyzing the symbols it recognizes and matching them to possible characters in its internal library.Since the OCR software already has some associations built between the characters in a document and the rules it already knows, this second scan can ensure higher accuracy in what it assumes each character to be. Many bank apps will allow customers to deposit checks from their phones via photograph.OCR software is only part of a larger OCR system composed of other software and hardware components.OCR software is capable of recognizing text in images that originate from scanners, cameras or PDF generators.Jazmine is a Research Specialist focusing on content management and collaboration software at G2 Crowd.She earned her Bachelor’s in psychology from the frozen tundra of the University of Illinois at Urbana-Champaign.
