The contrast between text and background is a prime factor.

As a rule, images that are dirty or damaged, or printed on wrinkled paper are more difficult for the OCR software to detect. This allows the retrieval of scanned images based upon their content.Īdditional considerations when selecting optical character recognition software include the quality and contrast of the scanned image.

Pattern recognition, artificial intelligence, and machine vision are used to convert scanned images into text that is then added to searchable databases.

Some OCR software and OCR systems are capable of reproducing formatted outputs that closely approximate the original document, in terms of images, columns, and other non-textual components.

The OCR software then checks whole words and matches them against a standard and/or custom dictionary. After the text is selected, OCR, software analyzes and interprets each character.

Some optical character recognition software allows the data following a search to be stored for future use. Search features vary among OCR systems.Adjustable selection criteria allows the user to select either an entire document for scanning, or specific parts or chapters.OCR software is available with a variety of features that best match the desired application.

The default output format for OCR software is usually a PDF file. OCR software can also create Excel files out of printed tables or HTML files out of complicated text and image layouts mixing the image binary files with text content and tags. They can also create a digital image file such as JPEG, GIF, or PNG, if there is no scannable text, or if the paper is all images. This is used in most cases to create modern digital records out of traditional paper archives, or in general to convert the old media to the new media.

These applications are fine for personal use but may not be adequate for heavy professional use or for difficult-to-read images. There are also free, or low-price, open source versions available on the web. Most Windows OS computers have a basic OCR program built into the standard photo-fax viewer application that will work with a standard PC-capable scanner. This versatility is the main advantage of a software based system versus the older dedicated OCR machines. OCR software today can be used on many different computers attached to a wide variety of scanning devices. This shift was accomplished through advances in power, speed, and storage of personal computers.

Like most digital processes, OCR devices evolved from dedicated hardware machines with specialized circuit boards and limited computing and storage power to the current software-based processes. It then creates a text document based on the characters it recognized. OCR software works by analyzing a document and comparing the text with all the different text fonts stored in the software’s database or by noting shapes and features common to most characters. Organizations use optical character recognition software to reduce data-entry errors and speed the processing of older paper or image-based archives. This process is also known as scan-to-text. The digital text can then be opened and used with desktop publishing software, word processing, and other computer applications. Optical character recognition software, or OCR software, translates images of printed, handwritten, or typewritten text into a computer editable digital, usually ASCII, text format.
