Search of similar features representing objects in a large reference database |
摘要 |
This invention is a method dedicated to pseudo-invariant features retrieval and, more particularly, applied to content-based copy identification. The range of a query is computed during the search according to deviation statistics between original and observed features. This approximate search range is directly mapped onto a Hilbert's space-filling curve allowing an efficient access to the database. Such a method is sublinear in database size and does not suffer from dimensionality problems.
