<p>Combined with the Leptonica Image Processing Library Tesseract can read a wide variety of image formats and convert them to text in over 40 languages.</p><p></p><p>This code is a raw OCR engine. It has no output formatting and no UI. It can detect fixed pitch vs proportional text. Nevertheless in 1995 this engine was in the top 3 in terms of character accuracy, and it compiles and runs on both Linux and Windows. Training code is included in the open source release.</p><p></p><p>The core developer on the project is Ray Smith (theraysmith).</p><p></p><p>Thomas Breuel (tmbdev) and Ilya Mezhirov (mezhirov) work on the OCRopus project, for which Tesseract is one of the pluggable OCR engines; OCRopus also provides layout analysis and statistical language modeling.</p><p></p><p>Most of the work on Tesseract is sponsored by Google.</p>
