getGuardObject

Method Detail

getFP

float[] getFP()

Gets the float array representation of the fingerprint.

The returned array might be the the internal representation array so changing the values is forbidden. Please note that this behavior is not guaranteed, the returned array can be a non cached copy of the represented vector generated on every invocation.

Returns:

float array

getEuclideanNorm

double getEuclideanNorm()

Euclidean norm of the represented vector.

Note that the actual implementation might or might not cache the returned value.

Returns:

Square root of the sum of the squares of the coordinates

getManhattanNorm

double getManhattanNorm()

Manhattan norm of the represented vector.

Note that the actual implementation might or might not cache the returned value.

Returns:

Sum of the squares of the coordinates

getMaximumNorm

double getMaximumNorm()

Maximum norm of the represented vector.

Note that the actual implementation might or might not cache the returned value.

Returns:

Maximum of the absolute values of the coordinates
