I count seven mistakes (five spelling, one capitalization, and one punctuation) in 266 words. For the sake of comparison, this listing is TesseractвЂ™s output on the exact same file with which I tested Kooka in the earlier review. This is an OCR engine that actually works. Now, the question is: how well does Tesseract compare to the open source competition? In January, I wrote an overview of free software OCR engines, concluding pessimistically that if you needed to OCR text of any length, you should consider paying a typist to transcribe it. Also, it can generate output only in the US-ASCII character set, so glyphs with accent marks or other unsupported attributes will probably be reproduced incorrectly. Just execute tesseract example.tiff outputfilename, and Tesseract will generate an ASCII file named outputfilename.txt containing the text recognized from example.tiff.Д¬urrently, Tesseract recognizes only English and works only on TIFF files (black and white, 8-bit greyscale, and 24-bit color no compression). The usage instructions are concise - Tesseract has no switches and does exactly one thing. Make sure the directory is writable, because Tesseract generates temporary files there while processing an image. In fact, you must move the resulting tesseract binary into its parent directory, where it expects to find a support directory called tessdata.

The only compilation instructions are those listed on the release notes section of the download page. You can download the latest tarball, a bugfix release numbered 1.0.1, from the Tesseract OCR project page.

Google spent a few months updating the code to compile on modern operating systems, and released it on. ISRI discovered that original Tesseract developer Ray Smith was now an employee at Google, and asked the search engine giant if it was interested in the code. Then in 2005, HP handed off the code to UNLVвЂ™s Information Science Research Institute (ISRI), an academic center doing ongoing research into OCR and related topics. In 1995, it was one of the top-tier performers at UNLVвЂ™s OCR competition, but when HP withdrew from the OCR software marketplace, the code languished. The Tesseract code was written at Hewlett-Packard in the 1980s and вЂ™90s.
