Decided to try Google's Search by Images option today. For those who aren't familiar with it, you can actually drag-and-drop an image into Google to search for related images or information on the image. I recall how I used to joke around with some friends that Google might at some point not even need any words plugged into it to find stuff.
Looks like we are here.
For testing, I tried throwing in an image of me and Rocky, a picture we took some months back.
The results were fun:
Google was able to find the blogpost where I had the picture featured, presumably by searching for the title of the file, and comparing it with other specific information it had extracted from the image (everything from dimensions to resolution, etc I would assume).
I found the Visually similar images very FUNNY though! Many of them clearly reflected the dominant colors in the image. Some tried to reflect whether it had two people or not. All in all, an amusing system.
Try it out!
