A fost publicat release-ul sistemului de recunoa\u0219tere optic\u0103 a textului Tesseract 4.1, care suport\u0103 recunoa\u0219terea caracterelor UTF-8 \u0219i a textelor \u00een peste 100 de limbi, inclusiv rus\u0103, kazah\u0103, belarus\u0103 \u0219i ucrainean\u0103. Rezultatul poate fi salvat at\u00e2t ca text brut, c\u00e2t \u0219i \u00een formate HTML (hOCR), ALTO (XML), PDF \u0219i TSV. Sistemul a fost ini\u021bial creat \u00eentre 1985 \u0219i 1995 \u00een laboratorul companiei Hewlett Packard, iar \u00een 2005 codul a fost deschis sub licen\u021ba Apache \u0219i a fost dezvoltat ulterior cu participarea angaja\u021bilor Google. Codul surs\u0103 al proiectului este distribuit sub licen\u021ba Apache 2.0. <\/p>\n
Tesseract include o utilitate de consol\u0103 \u0219i biblioteca libtesseract pentru integrarea func\u021biilor de recunoa\u0219tere a textului \u00een alte aplica\u021bii. Printre interfe\u021bele GUI ter\u021b\u0103 parte care suport\u0103 Tesseract se num\u0103r\u0103 gImageReader, VietOCR \u0219i YAGF. Ofer\u0103 dou\u0103 motoare de recunoa\u0219tere: clasic, care recunoa\u0219te textul la nivel de \u0219ablon pentru caractere individuale, \u0219i noul, bazat pe aplicarea unui sistem de \u00eenv\u0103\u021bare automat\u0103 bazat pe re\u021bele neuronale recurente LSTM, optimizat pentru recunoa\u0219terea \u00eentregilor linii \u0219i care permite o \u00eembun\u0103t\u0103\u021bire semnificativ\u0103 a preciziei. Modelele antrenate sunt publicate pentru 123 de limbi. Pentru optimizarea performan\u021bei, sunt disponibile module care folosesc OpenMP \u0219i instruc\u021biuni SIMD AVX2, AVX, NEON sau SSE4.1. <\/p>\n
