Tso tawm lub khoos phis tawj pom kev pom OpenCV 4.2

coj qhov chaw pub dawb tsev qiv ntawv tso tawm Qhib CV 4.2 (Open Source Computer Vision Library), uas muab cov cuab yeej rau kev ua thiab tshuaj xyuas cov ntsiab lus duab. OpenCV muab ntau tshaj 2500 algorithms, ob qho tib si classic thiab xav txog qhov kev nce qib tshiab hauv computer vision thiab machine learning systems. Lub tsev qiv ntawv code sau hauv C ++ thiab faib los ntawm nyob rau hauv BSD daim ntawv tso cai. Bindings tau npaj rau ntau hom lus programming, suav nrog Python, MATLAB thiab Java.

Lub tsev qiv ntawv tuaj yeem siv los paub txog cov khoom hauv cov duab thiab cov yeeb yaj kiab (piv txwv li, paub lub ntsej muag thiab cov duab ntawm tib neeg, ntawv nyeem, thiab lwm yam), taug qab kev txav ntawm cov khoom thiab lub koob yees duab, faib cov yeeb yaj kiab hauv video, hloov cov duab, rho tawm 3D qauv, tsim 3D qhov chaw los ntawm cov duab los ntawm cov koob yees duab tso suab, tsim cov duab zoo los ntawm kev sib txuas cov duab zoo nkauj, tshawb xyuas cov khoom hauv cov duab uas zoo ib yam li cov txheej txheem nthuav tawm, siv cov txheej txheem kev kawm tshuab, tso cov cim, txheeb xyuas cov ntsiab lus sib txawv. cov duab, cia li tshem tawm qhov tsis xws luag xws li qhov muag liab.

Π’ tshiab tso tawm:

  • Ib qho backend rau kev siv CUDA tau ntxiv rau DNN (Deep Neural Network) module nrog rau kev siv tshuab kev kawm algorithms raws li neural networks thiab kev sim API txhawb nqa tau siv. nGraph OpenVINO;
  • Siv cov lus qhia SIMD, cov lej ua haujlwm tau zoo rau cov tso zis tso suab (StereoBM/StereoSGBM), resizing, npog, kev sib hloov, suav cov xim uas ploj lawm thiab ntau lwm yam haujlwm;
  • Ntxiv ntau txoj xov siv los ntawm kev ua haujlwm pyrDown;
  • Ntxiv lub peev xwm los rho tawm cov yeeb yaj kiab los ntawm cov thawv ntim khoom (demuxing) siv cov videoio backend raws li FFmpeg;
  • Ntxiv algorithm rau ceev zaus-xaiv rov tsim kho cov duab puas FSR (Frequency Selective Reconstruction);
  • Ntxiv txoj kev RIC rau interpolation ntawm ib txwm unfilled cheeb tsam;
  • Ntxiv txoj kev sib txawv normalization logos;
  • G-API module (opencv_gapi), uas ua raws li lub cav rau kev ua haujlwm zoo ntawm cov duab siv graph-based algorithms, txhawb nqa ntau qhov kev sib txuas ntawm lub computer tsis pom kev thiab sib sib zog nqus tshuab kawm algorithms. Kev them nyiaj yug rau Intel Inference Engine backend yog muab. Ntxiv kev txhawb nqa rau kev ua cov kwj video rau cov qauv ua tiav;
  • Tshem tawm yooj yim (CVE-2019-5063, CVE-2019-5064), uas tuaj yeem ua rau muaj kev tawm tsam kev ua txhaum cai thaum ua cov ntaub ntawv tsis tau lees paub hauv XML, YAML thiab JSON hom. Yog tias tus cwj pwm nrog tus lej tsis raug raug pom thaum lub sijhawm JSON parsing, tag nrho tus nqi raug theej rau qhov tsis, tab sis tsis tau kuaj xyuas seb nws puas dhau ntawm thaj tsam ntawm thaj chaw nco.
