Avaldasime Tesseract 4.1 optilise tekstituvastuse s\u00fcsteemi, mis toetab UTF-8 kodeeringu ja enam kui 100 keele, sealhulgas vene, kasahhi, valgevene ja ukraina, tuvastamist. Tulemused v\u00f5ivad s\u00e4ilida nii avatud tekstina kui ka HTML (hOCR), ALTO (XML), PDF ja TSV formaatides. S\u00fcsteem loodi algselt 1985\u20131995 Hewlett Packardi laboris, kood avati 2005. aastal Apache litsentsi alusel ja edaspidi arendati seda Google'i t\u00f6\u00f6tajate kaasabil. Projekti allikakood jaotatakse Apache 2.0 litsentsi alusel. <\/p>\n
Tesseract h\u00f5lmab k\u00e4surea utiliiti ja libtesseract teeki, et integreerida tekstituvastuse funktsioone teistesse rakendustesse. Tesseracti toetavatest kolmandate osapoolte GUI-dest v\u00f5ib mainida gImageReader, VietOCR ja YAGF. Pakutakse kahte tunnustust: klassikaline, mis tuvastab s\u00fcmbolite \u00fcksikute mustrite tasemel, ja uus, mis p\u00f5hineb s\u00fcva\u00f5ppe s\u00fcsteemil, mille aluseks on LSTM rekurentne n\u00e4rviv\u00f5rk, mis on optimeeritud terve rida tunnustamiseks ja v\u00f5imaldab saavutada m\u00e4rkimisv\u00e4\u00e4rset t\u00e4psuse suurendamist. Koolitatud mudelid on avaldatud 123 keele jaoks. T\u00f5hususe optimeerimiseks on pakkuda mooduleid, mis kasutavad OpenMP ja SIMD-jochtude AVX2, AVX, NEON v\u00f5i SSE4.1. <\/p>\n
