Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for obtaining image search results. One of the methods includes aligning each image in a collection of near duplicate images to a common coordinate frame. One or more visual words are determined in the common coordinate frame for each of the images in the collection of near duplicate images. A union of visual words is determined, wherein the union of visual words comprises determined visual words in the common coordinate frame. A posting list item that identifies the collection of near duplicate images is added to one or more corresponding posting lists, wherein each posting list identifies one or more collections of near duplicate images whose union of determined visual words have the particular visual word.
