Last week, Google launched some algorithms changes to its Search by Image. You can try out Search by Image by simply uploading or dragging-and-dropping a photo into the search box on Google Images. Here some of these recent changes:
Smarter best guesses
Now, when you search with an image, Google uses computer vision to try and figure out what the image represents, and then show a "Best guess for this image." For instance, now you'll see that the image above is not just a "flower," but more specifically, that it is a bird of paradise, which is popular in Hawaii.
However, "we've made recent improvements to provide "best guesses" for more images more often and make the guesses more accurate. There are times when we may get it wrong or we won't show any guess at all," Google said.
Knowledge Graph results
Search by Image now uses the Knowledge Graph: Google says, now if you search with an image that they're able to recognize, you may see an extra panel of information along with your normal search results so you can learn more. "This could be a biography of a famous person, information about a plant or animal, or much more," informs Sean O'Malley, Software Engineer.
More comprehensive search results
With the recent improvements to freshness of results, "when photos of major news stories start appearing on the Internet, you can often find the news stories associated with those photos within minutes of the stories being posted," informs Sean.
Also, Google has expanded its index so you can find more sites that contain your image and information related to it.
Now, you see more information and sites with that image:

Tip: In Chrome or Firefox 3.0+, images from the Knowledge Graph area can be dragged into the search box to start another search! You can also download the Chrome or Firefox extensions to make searching photos from any website even easier.
