\u00c8 stata pubblicata la versione del sistema di riconoscimento ottico dei caratteri Tesseract 4.1, che supporta il riconoscimento dei caratteri UTF-8 e testi in oltre 100 lingue, tra cui russo, kazako, bielorusso e ucraino. I risultati possono essere salvati sia come testo aperto che nei formati HTML (hOCR), ALTO (XML), PDF e TSV. Inizialmente, il sistema \u00e8 stato creato tra il 1985 e il 1995 nel laboratorio della Hewlett Packard; nel 2005, il codice \u00e8 stato reso pubblico sotto licenza Apache e in seguito \u00e8 stato sviluppato con la partecipazione di dipendenti di Google. I testi sorgenti del progetto sono distribuiti sotto licenza Apache 2.0. <\/p>\n
Tesseract include un'utilit\u00e0 da console e una libreria libtesseract per integrare le funzioni di riconoscimento del testo in altre applicazioni. Tra le interfacce GUI di terze parti che supportano Tesseract, si possono citare gImageReader, VietOCR e YAGF. Sono disponibili due motori di riconoscimento: uno classico, che riconosce il testo a livello di modelli di singoli caratteri, e un nuovo motore che sfrutta un sistema di apprendimento automatico basato su una rete neurale ricorrente LSTM, ottimizzato per il riconoscimento di intere righe, consentendo di ottenere un notevole aumento della precisione. Modelli gi\u00e0 addestrati sono stati pubblicati per 123 lingue. Per ottimizzare le prestazioni, vengono proposti moduli che utilizzano OpenMP e istruzioni SIMD AVX2, AVX, NEON o SSE4.1. <\/p>\n
