The Internet giant has explained how to use the new feature, by giving an example of a user searching for images of tabby cats. “Now with the Similarity Search feature, you can simply hover over an image of a cat and click the ‘…’ menu. From there, Flickr will show you photos that look similar. No more guessing the search terms that would give you the most relevant results!” the company said in its release.
As the technique makes use of deep neural networks to find the similarity based on the semantic content of two images, it is further expected to improve over time. “We have been using deep neural networks at Flickr for a while for various tasks such as object recognition, NSFW prediction, and even prediction of aesthetic quality,” Clayton Mellina, Software Development Engineer at Yahoo, said in a post. If you need to understand the process of determining similar images, you can head to Mellina’s post and read the detailed explanation of the process.
