Die Ergebnisse k\u00f6nnen sowohl als Klartext als auch in den Formaten HTML (hOCR), ALTO (XML), PDF und TSV gespeichert werden. Urspr\u00fcnglich wurde das System in den Jahren 1985-1995 im Labor von Hewlett Packard entwickelt. Im Jahr 2005 wurde der Code unter der Apache-Lizenz ver\u00f6ffentlicht und sp\u00e4ter mit der Beteiligung von Google-Mitarbeitern weiterentwickelt. Die Quelltexte des Projekts werden unter der Lizenz Apache 2.0 verteilt.    <\/p>\n<p>Tesseract beinhaltet ein Konsolen-Utility und die Bibliothek libtesseract zur Integration von Textanerkennungsfunktionen in andere Anwendungen. Zu den unterst\u00fctzenden GUI-Schnittstellen von Drittanbietern f\u00fcr Tesseract geh\u00f6ren gImageReader, VietOCR und YAGF. Es werden zwei Erkennungs-Engines angeboten: eine klassische, die Text auf der Grundlage von Mustern einzelner Zeichen erkennt, und eine neue, die auf einem maschinellen Lernsystem mit rekurrenten neuronalen Netzwerken (LSTM) basiert, das f\u00fcr die Erkennung ganzer Zeilen optimiert ist und zu einem signifikanten Anstieg der Genauigkeit f\u00fchrt. Fertige trainierte Modelle sind f\u00fcr 123 Sprachen ver\u00f6ffentlicht worden. Zur Optimierung der Leistung werden Module angeboten, die OpenMP und SIMD-Befehle wie AVX2, AVX, AVX512F, NEON oder SSE4.1 verwenden.     <\/p>\n<p>Hauptverbesserungen:  <\/p>\n<ul>\n<li class=\"l\">

implementiert.\n<li class=\"l\"> Das Rendering im PDF-Format wurde verbessert.\n<li class=\"l\"> Die API zur Textneigungserkennung wurde erweitert.\n<li class=\"l\"> Leistungsprobleme, die beim
