Since the time last year, when Google launched Search by Image, people do begin to love it, and now making it more workable for the end users, Google updated the algorithm that powers this feature. Starting with the first feature, smarter best guesses, when you search with an image, the Google’s system will use computer vision and will figure out what you are looking for, and then based on best guess will show you a “Best guess for this image.”
Other feature, Knowledge Graph results, Google is starting to understand the world the way people do. Instead of treating webpages as strings of letters, now understand the concepts behind these words. Last but not the least, more comprehensive search results, finding more information about an image is the most common use of Search by Image. Google improves this too, so 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.
