Just need an approximate location and the SIFT descriptor for the object viewed from that location. Then a photo that is taken from that approximate location may or may not have the same SIFT descriptor (depending on visibility), which is a desirable result anyway. That does mean that the same object will have different SIFT descriptors as the location changes, so that's the unique part that a location DNS would need to handle. -- [EMAIL PROTECTED] _______________________________________________ Geowanking mailing list [email protected] http://lists.burri.to/mailman/listinfo/geowanking
