Once those patterns were located, the software could translate the characters into searchable, editable text in a document format. The earliest versions of character recognition developed in the 1960s relied on pattern recognition techniques, which scanned images and searched for pixel patterns that matched a backlog of font characters stored in memory. Programmers must provide them with clear parameters that help them to navigate unexpected variations and identify characters accurately. When humans read text, they have a mental concept of what the letter “a” looks like, but that concept is incredibly flexible and can easily accommodate a broad range of variations. For example, a computer must be able to recognize that each of the following characters is an “a”: That’s because there are so many different text fonts that depict the same characters in different ways. Unfortunately, even this isn’t as straightforward as it sounds. Character recognition technology helps computers distinguish text by telling them what patterns to look for.

The problem is that when a computer examines an image, it doesn’t see people, backgrounds, or text as distinct images, but rather as a pattern of pixels. In reality, getting a computer program to correctly identify text and convert it into editable format is an incredibly complex challenge complicated by a wide range of variables. Since the process involves something that humans can do quite easily (namely, reading text), it’s easy to assume that this would be a rather trivial task for a computer to accomplish. How Does Character Recognition Technology Work?Ĭharacter recognition technology allows computer software to read and recognize text contained in an image and then convert it into a document that can be searched or edited. While they perform very similar tasks, there are some key differences between them that developers need to keep in mind as they build their document and form processing applications. Much of transition was made possible by the proliferation of optical character recognition (OCR) and intelligent character recognition (ICR).

Error-prone manual processes have largely given way to automated document and forms processing technology that can turn scanned documents into a more manageable form with a much higher degree of accuracy. In OCR the colour is crucial as it decreases the size of the scanner’s output and increases the accuracy.The days of manually transcribing scanned documents into an editable, digital document are thankfully long behind most organizations. Respondents place one character in each box on this form.

For recognizing an image, it uses the registration marks at the four corners of the document. OCR provides flexibility due to the absence of the timing tracks or blocks. The special thing about the converted scanned images is that these can also be edited in a word processing software. OCR (Optical Character Recognition) uses the scanner and the special softwares to change the form of the printed text into scanned images. However, the accuracy attained by OMR can be greater than in the case of OCR if it is designed properly. The bubble in the OMR sheet must be precisely placed, and the cuts are also carved in a precise order. It also contains form ID marks that resemble to black boxes situated on the top or bottom of the form. It is comprised of timing tracks at the one edge of the form, and these tracks signify the place from where the scanner starts reading marks. The OMR is functionable with an only special document. It is mainly used as an input method for inserting a huge amount of data such as in answer sheet containing the answers of the multiple-choice questions. The job of an OMR (Optical Mark Recognition) reader is to detect the marks located at some specific positions on printed forms.
