Computer vision, explained simply
Computer vision teaches machines to see. It can find faces, read signs, spot objects and describe scenes.
It is behind phone photo search, camera filters, self checkout and car safety features.
This matters because pictures are everywhere, and computers can now sort and understand them quickly.
Vision systems can make mistakes or be biased by their training pictures. Human checks still matter for important decisions.
On ITG Now, free tool guides and AI research page stories cover vision tools, from object finders to image readers.
