500px, the Toronto-based image sharing site, has just released the Splash search engine, a novel way of finding images online. With other search engines, finding the right image can be difficult. Users either have to think up a search term and get lucky, or else have a similar image on hand (since Google can search with images.) Splash changes image searching by letting users draw what they want to see, freeing them to find exactly the type of image they need.
To find images, the Splash search engine uses its machine learning algorithm to hunt through 500px's database of photos. Though the database is less extensive than Google or Flickr, the results still tend to be very close to the drawn image in terms of composition and color.
