Kuxazululiwe: Idethi ye-Clone

Inkinga enkulu ehlobene nedethi ye-clone ukuthi ingadala ukudideka okuningi. Kungaba nzima ukucacisa ukuthi i-clone idalwe nini, futhi lokhu kungaholela ezinkingeni lapho uzama ukuphatha noma ukulandelela ama-clones.

I-OpenCV

I-OpenCV iwumtapo wolwazi wokubona ngekhompyutha nokufunda ngomshini. Ingasetshenziselwa ukucubungula nokuhlaziya izithombe, amavidiyo, nenye idatha. I-OpenCV ingasetshenziswa ezinhlelweni ezahlukahlukene, njengokuhlela isithombe, ukuhlela ividiyo, amakhamera okuvikela, nokuningi.

Khipha ibhokisi lokubopha

Khipha ibhokisi elibophayo ku-JavaScript kuwumsebenzi olula futhi olula. Ungasebenzisa ikhodi elandelayo ukukhipha ibhokisi elibophayo lento.

var obj = {}; obj.x = 100; obj.y = 200; // Khipha ibhokisi elibophezelayo le-obj var bbox = obj.bounds();

Ikhodi engenhla izobuyisela into yemingcele elandelayo:

{x: 100, y: 200}
