Ukukhishwa kohlelo lokuqaphela umbhalo we-Tesseract 5.2 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, kanye nentsha esekelwe ekusetshenzisweni kwesistimu yokufunda yomshini esekelwe kunethiwekhi ye-neural eqhubekayo ye-LSTM, elungiselelwe ukubona amayunithi ezinhlamvu wonke kanye nokuvumela ukwanda okuphawulekayo kokunemba. Amamodeli asevele enziwe aqeqeshiwe ashicilelwe ngezilimi eziyi-123. Ukuze uthuthukise ukusebenza, amamojula asebenzisa imiyalelo ye-OpenMP ne-SIMD AVX2, AVX, AVX512F, NEON noma SSE4.1.
Ukuthuthukiswa okukhulu ku-Tesseract 5.2:
- Ukulungiselelwa okungeziwe okusetshenziswa kusetshenziswa imiyalelo ye-Intel AVX512F.
- I-C API isebenzisa umsebenzi wokuqalisa i-tesract ngokulayisha imodeli yokufunda yomshini kusuka kumemori.
- Kwengezwe ipharamitha ye-invert_threshold, enquma izinga lokuguqulwa kweyunithi yezinhlamvu zombhalo. Inani elizenzakalelayo lingu-0.7. Ukuze ukhubaze ukuguqulwa, setha inani ku-0.
- Ukucubungula okuthuthukisiwe kwamadokhumenti amakhulu kakhulu kubasingathi be-32-bit.
- Uguquko lwenziwe kusukela ekusebenziseni imisebenzi ye-std::regex kuya ku-std::string.
- Izikripthi zokwakha ezithuthukisiwe ze-Autotools, i-CMake nezinhlelo zokuhlanganisa eziqhubekayo.
