Google now let you use Google Images with sorting. Sorting will be rolling out globally to nearly every domain and language over the next week.
"Now, when you search for [london], by default you'll see image results ranked by relevance. Click "Sort by subject" in the left-hand panel and you'll see images organized into categories that'll narrow down your search and help you find the exact image of London that you want," Google informed.
"Sorting by subject shows that some of the most popular images associated with London are the London Eye, Big Ben, Tower Bridge and the city at night. This organized view helps you find the images you were visualizing more quickly, so you might realize, "Ah, that big clock tower is called Big Ben, that's what I was looking for." You can then can click on the Big Ben group to find the best image within that subject group," explains Google
"You can also use this feature to explore categories of a general topic that may be easier to learn about visually, like flower varieties or dog breeds."
"Sorting by subject uses algorithms that identify relationships among images found on the web and presents those images in visual groups, expanding on the technology developed for Google Similar Images and Google Image Swirl. By looking at multiple sources of similarities, such as pixel values and semantic relationships, and by mining massive amounts of data, we can make meaningful connections and groupings among images," Google explained.
