Method for fast return of abstracted images from a digital images database
First Claim
Patent Images
1. A method for identifying a match for a target digital image from among a set of candidate digital images, comprising:
- (a) identifying at least one candidate salient point set from at least one of said candidate digital images;
(b) identifying a target salient point set from said target digital image;
(c) comparing said at least one candidate salient point set to said target salient point set;
(d) for each said at least one said candidate digital image marking said candidate digital image for further inspection if said candidate salient point set meets a similarity threshold with said target salient point set;
(e) identifying another target salient point set from said target digital image;
(f) for each said candidate digital image marked for further inspection identifying another candidate salient point set; and
(g) if said database image has been marked for further inspection, comparing said another target salient poiint set with said another candidate salient point set and marking said candidate image for yet further inspection if said another candidate salient point set meets a similarity threshold with said another target salient point set.

Abstract
A method for expediting a search of a digital image database comprises, for each digital image, constructing a set of at least two abstracted images varying in level of detail and searching the abstracted images. Selected ones of the abstracted images are down-loaded to a user thereby reducing download time through a finite bandwidth communicative medium relative to the time needed to download complete digital images.
