Abstract:
Visual fingerprinting is used to provide a robust and highly effective method of finding similar content in a large document collection of rich document content composed of multiple text, line-art, and photo image objects. The visual fingerprints capture unique two-dimensional localized aspects of document appearance. The visual fingerprints are highly distinctive; fast for lookup; compact for storage requirements; and scalable to large document collections.
