Laeborari ea mahala ea OpenCV 4.7 (Open Source Computer Vision Library) e ile ea lokolloa, e fana ka lisebelisoa tsa ho sebetsana le ho hlahloba litaba tsa litšoantšo. OpenCV e fana ka li-algorithms tse fetang 2500, tsa khale ebile li bonts'a tsoelo-pele ea morao-rao ponong ea komporo le lits'ebetso tsa ho ithuta ka mochini. Khoutu ea laeborari e ngotsoe ka C ++ mme e ajoa tlasa laesense ea BSD. Litlamo li lokiselitsoe lipuo tse fapaneng tsa lenaneo, ho kenyeletsoa Python, MATLAB le Java.
Laeborari e ka sebelisoa ho lemoha lintho tse lifoto le livideo (mohlala, ho lemoha lifahleho le lipalo tsa batho, mongolo, joalo-joalo), ho latela motsamao oa lintho le lik'hamera, ho hlophisa liketso ka video, ho fetola litšoantšo, ho ntša mefuta ea 3D, ho hlahisa sebaka sa 3D ho tloha litšoantšong tsa lik'hamera tsa stereo, ho etsa litšoantšo tsa boleng bo phahameng ka ho kopanya litšoantšo tsa boleng bo tlaase, ho batla lintho tse setšoantšong tse tšoanang le sete e hlahisitsoeng ea likarolo, ho sebelisa mekhoa ea ho ithuta mochine, ho beha matšoao, ho khetholla lintho tse tloaelehileng ka litsela tse fapaneng. litšoantšo, ka tsela e iketsang ho tlosa likoli tse kang red-eye .
Har'a liphetoho tse hlahang tokollong e ncha:
- Ntlafatso e kholo ea ts'ebetso ea convolution mojuleng oa DNN (Deep Neural Network) e entsoe ka ts'ebetsong ea li-algorithms tsa ho ithuta mochini tse thehiloeng ho marang-rang a neural. Winograd fast convolution algorithm e se e kentsoe tšebetsong. E ekelitse likarolo tse ncha tsa ONNX (Open Neural Network Exchange): Scatter, ScatterND, Tile, ReduceL1 le ReduceMin. Ts'ehetso e ekelitsoeng bakeng sa moralo oa OpenVino 2022.1 le backend ea CANN.
- Boleng bo ntlafetseng ba ho lemoha le ho hlophisa khoutu ea QR.
- Ts'ehetso e ekelitsoeng bakeng sa matšoao a bonoang ArUco le AprilTag.
- E kentse tracker ea Nanotrack v2 e thehiloeng ho marang-rang a neural.
- E kentse algorithm ea ho fifala ha Stackblur.
- Tšehetso e ekelitsoeng bakeng sa FFmpeg 5.x le CUDA 12.0.
- Ho hlahisitsoe API e ncha bakeng sa ho laola lifomate tsa litšoantšo tsa maqephe a mangata.
- Tšehetso e ekelitsoeng bakeng sa laeborari ea libSPNG bakeng sa sebopeho sa PNG.
- libJPEG-Turbo e thusa ho potlakisa ho sebelisa litaelo tsa SIMD.
- Bakeng sa sethala sa Android, tšehetso ea H264/H265 e kentsoe tšebetsong.
- Li-API tsohle tsa mantlha tsa Python li fanoe.
- E kentse backend e ncha ea bokahohle bakeng sa litaelo tsa vector.
