Unofficial: Search Google Images By Drawing

Oct 4, 2011 • 8:26 am | comments (5) by | Filed Under Google Search Engine

Franz Enzenhofer built this cool feature that lets you draw a picture (or take a picture of yourself with your webcam) and then search Google Images using the search by image feature based on your drawing.

I decided to draw elmo, which can often turn bad because I am not a good artist. But here is a video demo of it in action:

To play with this tool yourself, go to Franz's web site.

He explained how it works:

  • You draw something on an HTML5 canvas.
  • Click on Search
  • Image gets converted into a base64 encoded data uri
  • Image data gets send to server (powered by Heroku)
  • Image gets uploaded to Amazon S3
  • The Amazon S3 Image URL gets communicated back to your browser.
  • Browser gets redirected to Google Search by Image
Pretty smart!
