Lub tsev qiv ntawv dawb OpenCV 4.7 (Open Source Computer Vision Library) tau tso tawm, muab cov cuab yeej rau kev ua haujlwm 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 muab faib raws li 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.
Ntawm cov kev hloov pauv hauv qhov kev tso tawm tshiab:
- Qhov tseem ceeb optimization ntawm convolution kev ua tau zoo nyob rau hauv lub DNN (Deep Neural Network) module tau ua nrog rau kev siv tshuab kev kawm algorithms raws li neural networks. Winograd fast convolution algorithm tau ua tiav. Ntxiv tshiab ONNX (Qhib Neural Network Txauv) txheej: Scatter, ScatterND, Pobzeb, ReduceL1 thiab ReduceMin. Ntxiv kev txhawb nqa rau OpenVino 2022.1 lub moj khaum thiab CANN backend.
- Txhim kho qhov zoo ntawm QR code nrhiav thiab txiav txim siab.
- Ntxiv kev txhawb nqa rau cov cim pom ArUco thiab AprilTag.
- Ntxiv Nanotrack v2 tracker raws li neural networks.
- Implemented Stackblur plooj algorithm.
- Ntxiv kev txhawb nqa rau FFmpeg 5.x thiab CUDA 12.0.
- API tshiab tau raug thov rau kev tswj hwm ntau nplooj ntawv duab hom.
- Ntxiv kev txhawb nqa rau lub tsev qiv ntawv libSPNG rau hom PNG.
- libJPEG-Turbo enables acceleration siv SIMD cov lus qhia.
- Rau lub platform Android, kev txhawb nqa rau H264 / H265 tau ua tiav.
- Tag nrho cov Python APIs tau muab.
- Ntxiv ib tug tshiab universal backend rau vector cov lus qhia.
