Cloud Vision API: How it will Transform the Visual Recognition?

Consider a case where you search for a gadget in Google Image search. Your screen will be deluged with numerous images of it drawn from infinite quarters across world wide web. The logic behind surfacing these images is quite simple. If the image uploaded has a name, title and'alt' tag mentioned, that image will get picked by google crawlers. Another possibility is, even though the image might not have any such parameters, but if the web page content(where images reside) matches the search term, the image in that web page shows up. This works fluently if it was not been abused by black strategies.
