retrievr
A new service from the viennese company systemone:
Retrievr lets you find flickr images by drawing rough sketches of them. Finding images on Flickr is mostly textual (tags, keywords) or social (contacts, friends, groups). Retrievr is, like images, visual. At the same time it’s our testbed for image retrieval algorithms, so that when you add an image to a page in System One, it gets you the potentially most similar pictures back in realtime.
It was not fair to test the retrieval with my above flower image (big one to the left) , as it bears a lot of fine structure….and consequently I got the above results back (images to the right)…:)
