After a decade of minimal development it was released in 2005 for open source. It was initially developed at HP during a 10 year period from 1984 to 1994.

Between 19 it had little work done on it, but since then it has been improved extensively by Google.ĭevelopment of Tesseract is sponsored by Google. It was one of the top 3 engines in the 1995 UNLV Accuracy test. Combined with the Leptonica Image Processing Library it can read a wide variety of image formats and convert them to text in over 60 languages. Tesseract is probably the most accurate open source OCR engine available.
