Ho lokolloa ha Tesseract 5.2 optical text recognition system e hatisitsoe, e tšehetsang tlhokomelo ea litlhaku tsa UTF-8 le litemana ka lipuo tse fetang 100, ho akarelletsa Serussia, Kazakh, Belarusian le Seukraine. Sephetho se ka bolokoa ka mongolo o hlakileng kapa ka liforomo tsa HTML (hOCR), ALTO (XML), PDF le TSV. Sistimi e qalile ka 1985-1995 ka laboratoring ea Hewlett Packard; ka 2005, khoutu e ile ea buloa tlasa laesense ea Apache mme ea ntlafatsoa hape ka ho nka karolo ha basebetsi ba Google. Khoutu ea mohloli oa projeke e ajoa tlasa laesense ea Apache 2.0.
Tesseract e kenyelletsa sesebelisoa sa console le laeborari ea libtesseract bakeng sa ho kenya ts'ebetso ea OCR lits'ebetsong tse ling. Likhokahano tsa mokha oa boraro tsa GUI tse tšehetsang Tesseract li kenyelletsa gImageReader, VietOCR le YAGF. Ho fanoa ka lienjineri tse peli tsa temohisiso: ea khale e amohelang mongolo boemong ba lipaterone tsa motho ka mong, le e ncha e ipapisitseng le ts'ebeliso ea sistimi ea ho ithuta ka mochini e thehiloeng ho netweke ea LSTM e pheta-phetoang ea neural, e ntlafalitsoeng bakeng sa ho lemoha likhoele tse felletseng le ho lumella ho keketseho e kholo ea ho nepahala. Mefuta e seng e lokisitsoe e seng e hatisitsoe ka lipuo tse 123. Ho ntlafatsa ts'ebetso, ho fanoa ka li-module tse sebelisang OpenMP le SIMD AVX2, AVX, AVX512F, NEON kapa SSE4.1.
Lintlafatso tse kholo ho Tesseract 5.2:
- Lintlafatso tse kenyellelitsoeng ho sebelisoa litaelo tsa Intel AVX512F.
- C API e sebelisa ts'ebetso ea ho qala tesseract ka ho kenya mofuta oa ho ithuta oa mochini ho tsoa mohopolong.
- E kentse paramethara ea invert_threshold, e khethollang boemo ba phetoho ea likhoele tsa mongolo. Boleng ba kamehla ke 0.7. Ho tima inversion, beha boleng ho 0.
- Ts'ebetso e ntlafalitsoeng ea litokomane tse kholo haholo ho li-hosts tsa 32-bit.
- Phetoho e entsoe ho tloha ho std::regex function to std::string.
- Lingoliloeng tse ntlafalitsoeng bakeng sa Autotools, CMake le litsamaiso tse tsoelang pele tsa kopanyo.
