  • Equipment for the optical playback of analog phonographic records
    Patent number: 7660208
    Abstract: This invention relates to equipment for the optical playback of sound media which includes resources (1) that has engraves grooves, (3, 9) for generating at least one light beam that presents a light spectrum variation according to its incidence angle on an area of the sound media and an image sensor (7) placed so that it recovers the light reflected by said area of the sound media.

  • Search of similar features representing objects in a large reference database
    Patent number: 7400784
    Abstract: 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.
