Early versions needed to be trained with images of each character, and worked on one font at a time. Advanced systems capable of producing a high degree of recognition accuracy for most fonts are now common, and with support for a variety of digital image file format inputs. Early optical character character and Concept PDF may be traced to technologies involving telegraphy and creating reading devices for the blind.

Traditional virtue ethics and the widely accepted view of character that such ethical theorizing depends upon have recently come under attack by situationist philosophers. Most prominent among these philosophers is John Doris and Gilbert Harman. Situationism attempts to undermine the concept of character used to support most versions of virtue ethics by appealing to research on conformity in the social sciences. Such research is intended to show that robust character traits are an illusion. More specifically, both Doris and Harman are global character trait eliminativists who take the social-psychological research to warrant the abandonment of the concept of character. This book is an attempt to defend the standard notions of character from the concerns raised by situationists. It draws heavily upon the mental space mapping theory known as conceptual blending developed by Gilles Fauconnier and Mark Turner and makes use of the insights gleaned therefrom to disarm the situationists character eliminativist position. Primarily, this is done by showing how entrenched and useful is the notion of character to our common understandings and interpretations of ourselves and others.
In 1914, Emanuel Goldberg developed a machine that read characters and converted them into standard telegraph code. In the late 1920s and into the 1930s Emanuel Goldberg developed what he called a „Statistical Machine“ for searching microfilm archives using an optical code recognition system. In 1931 he was granted USA Patent number 1,838,389 for the invention. The patent was acquired by IBM. With the advent of smart-phones and smartglasses, OCR can be used in internet connected mobile device applications that extract text captured using the device’s camera. In 1974, Ray Kurzweil started the company Kurzweil Computer Products, Inc. Devanagari, Tamil, Chinese, Japanese, and Korean characters.
OCR engines have been developed into many kinds of domain-specific OCR applications, such as receipt OCR, invoice OCR, check OCR, legal billing document OCR. Data entry for business documents, e. More quickly make textual versions of printed documents, e. Make electronic images of printed documents searchable, e. Defeating CAPTCHA anti-bot systems, though these are specifically designed to prevent OCR. The purpose can also be to test the robustness of CAPTCHA anti-bot systems. This is especially useful for languages where glyphs are not separated in cursive script.
