2/27/2008

Compares a sample Biometrics Information Record against the entries of a collection of other Biometrics Information Records, and then returns a rank ordered array of indexes.

Namespace: Microsoft.PointOfService
Assembly: Microsoft.PointOfService (in microsoft.pointofservice.dll)

public abstract int[] IdentifyMatch (
    int maximumFalseAcceptRateRequested, 
    int maximumFalseRejectRateRequested, 
    boolean falseAcceptRatePrecedence, 
    BiometricsInformationRecord sampleBir, 
    IEnumerable<BiometricsInformationRecord> referenceBirPopulation
)

public abstract function IdentifyMatch (
    maximumFalseAcceptRateRequested : int, 
    maximumFalseRejectRateRequested : int, 
    falseAcceptRatePrecedence : boolean, 
    sampleBir : BiometricsInformationRecord, 
    referenceBirPopulation : IEnumerable<BiometricsInformationRecord>
) : int[]

Parameters

• maximumFalseAcceptRateRequested
  The requested FAR criterion for successful verification.

• maximumFalseRejectRateRequested
  The requested FRR criterion for successful verification.

  An EMPTY pointer indicates that this criterion is not provided.

• falseAcceptRatePrecedence
  If both criteria are provided, this parameter indicates which takes precedence. falseAcceptRatePrecedence indicates that maxFARRRequested takes precedence, falseRejectRatePrecedence indicates that maxFRRRequested takes precedence.

• sampleBir
  The BiometricsInformationRecord property to be identified.

• referenceBirPopulation
  An array of BiometricsInformationRecord properties against which the Identify match is performed.

Remarks

This function accepts a sampleir and compares it against a set of BiometricsInformationRecord properties in referenceBirPopulation. It then returns a rank ordered array of referenceBirPopulation indexes.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread-safe. Any instance members are not guaranteed to be thread-safe.
