Abstract:
1. A method for detecting and annotating landmarks in digital images: (a) automatically assigning, to one or more images in a plurality of text-associated digital images, a text tag descriptive of a landmark, to generate a set of landmark-tagged images, wherein images in the set of landmark-tagged images are algorithmically determined to include the landmark, wherein the text tag is based upon one or more scored n-grams from one or more texts associated with the one or more images, wherein the n-grams are scored by assigning correlation-weights to the plurality of text-associated digital images, and wherein the landmark identifies an object in or feature marking a geographic point or geographic area; (b) learning an appearance model for the landmark from the set of landmark-tagged images; and (c) detecting the landmark in a new image using the appearance model, wherein said stages (a)-(c) are performed by at least one processor.
