Laibulale yaulere OpenCV 4.7 (Open Source Computer Vision Library) idatulutsidwa, yopereka zida zosinthira ndi kusanthula zomwe zili pazithunzi. OpenCV imapereka ma aligorivimu opitilira 2500, onse akale komanso akuwonetsa kupita patsogolo kwaposachedwa pamawonekedwe apakompyuta ndi makina ophunzirira makina. Khodi ya library imalembedwa mu C ++ ndikugawidwa pansi pa layisensi ya BSD. Zomangira zimakonzedwera zilankhulo zosiyanasiyana zamapulogalamu, kuphatikiza Python, MATLAB ndi Java.
Laibulale ingagwiritsidwe ntchito kuzindikira zinthu pazithunzi ndi makanema (mwachitsanzo, kuzindikira nkhope ndi ziwerengero za anthu, zolemba, ndi zina), kutsatira kayendedwe ka zinthu ndi makamera, kugawa zochita m'mavidiyo, kutembenuza zithunzi, kuchotsa zitsanzo za 3D, kupanga malo a 3D kuchokera ku zithunzi kuchokera ku makamera a stereo, kupanga zithunzi zamtengo wapatali mwa kuphatikiza zithunzi zapansi, kufufuza zinthu zomwe zili m'chifaniziro zofanana ndi zomwe zaperekedwa, kugwiritsa ntchito njira zophunzirira makina, kuyika zolembera, kuzindikira zinthu zomwe zimafanana muzinthu zosiyanasiyana. zithunzi, kuchotsa zolakwika monga red-eye .
Zosintha pakutulutsa kwatsopano zikuphatikiza:
- Kukhathamiritsa kwakukulu kwa magwiridwe antchito mu gawo la DNN (Deep Neural Network) kwachitika ndikukhazikitsa ma algorithms ophunzirira makina potengera ma neural network. Winograd fast convolution algorithm yakhazikitsidwa. Onjezani zigawo zatsopano za ONNX (Open Neural Network Exchange): Scatter, ScatterND, Tile, ReduceL1 ndi ReduceMin. Thandizo lowonjezera la OpenVino 2022.1 chimango ndi CANN backend.
- Kuwongolera kwabwino kwa kuzindikira ma code a QR ndikusintha.
- Zowonjezera zothandizira zolembera zowoneka ArUco ndi AprilTag.
- Wowonjezera Nanotrack v2 tracker kutengera neural network.
- Anakhazikitsa Stackblur blur algorithm.
- Thandizo lowonjezera la FFmpeg 5.x ndi CUDA 12.0.
- API yatsopano yaperekedwa kuti isinthe mawonekedwe azithunzi zamasamba ambiri.
- Zowonjezera zothandizira laibulale ya libSPNG ya mtundu wa PNG.
- libJPEG-Turbo imathandizira mathamangitsidwe pogwiritsa ntchito malangizo a SIMD.
- Pa nsanja ya Android, chithandizo cha H264/H265 chakhazikitsidwa.
- Ma API onse oyambira a Python amaperekedwa.
- Adawonjezeranso njira yakumbuyo yapadziko lonse lapansi pamalangizo a vector.
