Kev tso tawm ntawm Tesseract 5.2 optical text recognition system tau luam tawm, txhawb kev lees paub ntawm UTF-8 cov cim thiab cov ntawv hauv ntau dua 100 hom lus, suav nrog Lavxias, Kazakh, Belarusian thiab Ukrainian. Cov txiaj ntsig tuaj yeem khaws cia hauv cov ntawv nyeem dawb lossis hauv HTML (hOCR), ALTO (XML), PDF thiab TSV hom. Lub kaw lus tau tsim nyob rau hauv 1985-1995 hauv Hewlett Packard laboratory; hauv 2005, cov cai tau qhib raws li daim ntawv tso cai Apache thiab tau tsim ntxiv nrog kev koom tes ntawm Google cov neeg ua haujlwm. Qhov chaws ntawm qhov project yog muab faib raws li Apache 2.0 daim ntawv tso cai.
Tesseract suav nrog kev siv hluav taws xob console thiab lub tsev qiv ntawv libtesseract rau embedding OCR functionality rau lwm yam kev siv. Thib peb GUI interfaces uas txhawb Tesseract suav nrog gImageReader, VietOCR thiab YAGF. Muaj ob lub cav paub txog: ib qho classic uas lees paub cov ntawv nyob rau theem ntawm tus kheej tus cwj pwm qauv, thiab ib qho tshiab raws li kev siv tshuab kev kawm raws li LSTM recurrent neural network, optimized rau paub tag nrho cov hlua thiab tso cai rau ib tug qhov tseem ceeb ntawm qhov tseeb. Cov qauv npaj ua tiav tau luam tawm rau 123 yam lus. Txhawm rau txhim kho kev ua tau zoo, cov qauv siv OpenMP thiab SIMD cov lus qhia AVX2, AVX, AVX512F, NEON lossis SSE4.1 muaj.
Kev txhim kho loj hauv Tesseract 5.2:
- Ntxiv kev ua kom zoo dua qub siv Intel AVX512F cov lus qhia.
- C API siv lub luag haujlwm los pib tesseract nrog thauj cov qauv kev kawm tshuab los ntawm kev nco.
- Ntxiv qhov invert_threshold parameter, uas txiav txim siab theem ntawm inversion ntawm cov kab ntawv. Tus nqi pib yog 0.7. Txhawm rau lov tes taw inversion, teeb tus nqi rau 0.
- Txhim kho kev ua cov ntaub ntawv loj heev ntawm 32-ntsis hosts.
- Qhov kev hloov pauv tau ua los ntawm kev siv std::regex functions rau std::string.
- Txhim kho tsim cov ntawv sau rau Autotools, CMake thiab txuas txuas txuas ntxiv.
