Resultatet kan gemmes som ren tekst eller i HTML-format (hOCR), ALTO (XML), PDF og TSV. Systemet blev oprindeligt udviklet fra 1985-1995 i laboratoriet hos Hewlett Packard, og i 2005 blev koden \u00e5bnet under Apache-licensen og har siden da v\u00e6ret videreudviklet med deltagelse af medarbejdere fra Google. Projektets kildekoder distribueres under Apache 2.0-licensen.    <\/p>\n<p>Tesseract inkluderer et kommandolinjev\u00e6rkt\u00f8j og biblioteket libtesseract til indbygning af tekstgenkendelsesfunktioner i andre applikationer. Blandt de eksterne GUI-gr\u00e6nseflader, der underst\u00f8tter Tesseract, kan n\u00e6vnes gImageReader, VietOCR og YAGF. Der tilbydes to genkendelsesmotorer: en klassisk, der genkender tekst p\u00e5 niveau med mallene for individuelle tegn, og en ny, der er baseret p\u00e5 anvendelsen af et maskinl\u00e6ringssystem med en rekurrent neural netv\u00e6rk (LSTM), optimeret til at genkende hele linjer og derved opn\u00e5 betydelig forbedring af n\u00f8jagtigheden. F\u00e6rdigtr\u00e6nede modeller er offentliggjort til 123 sprog. For at optimere ydeevnen tilbydes moduler, der bruger OpenMP og AVX2, AVX, AVX512F, NEON eller SSE4.1 SIMD-instruktioner.     <\/p>\n<p>Hovedforbedringer:  <\/p>\n<ul>\n<li class=\"l\"> Billedgenkendelsen via URL er forbedret med filupload ved hj\u00e6lp af libcurl-biblioteket.
