Ukukhishwa kohlelo lokuqaphela umbhalo we-Tesseract 5.1 kushicilelwe, okusekela ukuqashelwa kwezinhlamvu ze-UTF-8 nemibhalo ngezilimi ezingaphezu kuka-100, okuhlanganisa isiRashiya, isiKazakh, isiBelarusian nesi-Ukrainian. Umphumela ungagcinwa ngombhalo ongenalutho noma ngefomethi ye-HTML (hOCR), ALTO (XML), PDF kanye ne-TSV. Uhlelo lwaqalwa ngo-1985-1995 elabhorethri ye-Hewlett Packard; ngo-2005, ikhodi yavulwa ngaphansi kwelayisensi ye-Apache futhi yathuthukiswa futhi ngokubamba iqhaza kwabasebenzi bakwa-Google. Ikhodi yomthombo yephrojekthi isatshalaliswa ngaphansi kwelayisensi ye-Apache 2.0.
I-Tesseract ihlanganisa insiza yekhonsoli kanye nelabhulali ye-libtesseract yokushumeka ukusebenza kwe-OCR kwezinye izinhlelo zokusebenza. Izixhumanisi ze-GUI zenkampani yangaphandle ezisekela i-Tesseract zifaka i-gImageReader, i-VietOCR ne-YAGF. Kuhlinzekwa izinjini ezimbili zokuqaphela: eyakudala ebona umbhalo ezingeni lamaphethini omlingiswa ngamunye, nentsha esekelwe ekusetshenzisweni kwesistimu yokufunda yomshini esekelwe kunethiwekhi ye-neural eqhubekayo ye-LSTM, elungiselelwe ukubona wonke amayunithi ezinhlamvu kanye nokuvumela ukwanda okuphawulekayo kokunemba. Amamodeli asevele enziwe aqeqeshiwe ashicilelwe ngezilimi eziyi-123. Ukuze kuthuthukiswe ukusebenza, amamojula asebenzisa imiyalelo ye-OpenMP ne-SIMD ethi AVX2, AVX, NEON noma SSE4.1.
Ukuthuthukiswa okukhulu ku-Tesseract 5.1:
- Ikhono lokucubungula izindawo ezinezithombe nemigqa lapho ukhipha ku-ALTO, i-hOCR namafomethi ombhalo seliqalisiwe.
- Kwengezwe ipharamitha entsha curl_timeout lkz curl_easy_setop.
- Isistimu yokwakha ethuthukisiwe.
- Umsebenzi wenziwe ukususa ikhodi engasetshenziswanga
- Ukuphahlazeka okulungisiwe okudalwe ukuphatha okungalungile kwezikhombisi ezingenalutho ekilasini le-PageIterator::Orientation.
