Interactively browsing large image collections.

Manually locating an image in a large collection has become infeasible with the recent rapid growth in size of such collections. Nowadays, even private collections easily contain tens of thousands of images; public collections have long passed the billion images mark. Current approaches for finding images in large collections, therefore, try to confine the set of images by returning only those images that correspond to certain properties defined by a query. Such properties can include: keywords, semantic information associated with the images, similarity to an example image, a rough sketch of the desired outlines, or any combination thereof.
