Abrégé
A method including the steps of:) receiving (202) a search record; generating (206) at least one hierarchical cluster, each having a different minimum quality level; for each cluster, generating (210) at least one corresponding search package having a first set of search prints; selecting the highest quality cluster (218), a search package (222) and corresponding file records for performing a search (226); determining (230) whether a hit was found between any file print in the corresponding file records and any search print in the selected search package; and proceeding with the search process through the remaining quality clusters in an order based on decreasing quality until a match is found or until there are no remaining file records against which to compare a search package.

Abrégé
A system and a method for segmenting slap fingerprints is described. The method includes providing a print image, optionally pre-processing the print image, detecting at least a plurality of image components of the print image, determining at least one segmentation boundary for the print image, and computing the convex hull of the image components. The orientation, relative orientation and placement of the image components are detected. The zone lines of each component are found and zone areas are defined. The components under the top component of each zone are deleted. The finger numbers are assigned in accordance with the anchor print component, the geometrical relationship among the components. The slap print image is segmented in accordance with the segmentation boundary and its neighboring boundaries.

Abrégé
An automated digital processing system and method for characterizing the probability of a finger print match for at least one finger including a means for providing at least a plurality of match scores for at least one finger; a means for providing a finger index; a means for providing a number of fingers used in the search; a means for providing a number of times a finger index appears in a subset of probable matches; and a means for providing a number of records in the database. At least two record identification metrics are calculated and a means for calculating a match credibility metric of the calculated record identification metrics is provided based on a function of at least one of: the number of fingers used in the search, the first record identification metric, and the second record identification metric. A means for providing a user with at least one of the record identification metrics is further provided.

Abrégé
A system and a method for minutiae record matching is claimed that includes the processing a first plurality of ordered minutiae match values with weighting values corresponding to a function of at least the number of minutiae in the corresponding latent print and the corresponding print in the tenprint for a given unweighted match value to define a second plurality of weighted match values. The second plurality of weighted match values may be further normalized based at least on the highest unweighted match value to generated a third plurality of weighted match values.

Abrégé
An optical output device (164) includes a moncrystalline silicon substrate (102) and multiple light sources (168a-168n) formed of compound semiconductor materials. An accommodating buffer layer (104) lies between the light sources (168a-168n) and the substrate (102). An optical interconnect (170), such as a waveguide, is formed over the multiple light sources (168a-168n) and connects them to an output port (172). The accommodating buffer layer (104) is a layer of monocrystalline oxide spaced apart from the silicon substrate (102) by an amorphous interface layer (106) of silicon oxide, and is lattice matched to both the underlying silicon substrate (102) and the waveguide (170). Any lattice mismatch between the accommodating buffer layer (104) and the underlying silicon substrate (102) is taken care of by the amorphous interface layer (106).
