Required Methods

Provided Methods

Computes Signature Quadratic Form Distance of two signatures.

Parameters
  • _signature0: The first signature.
  • _signature1: The second signature.

Computes Signature Quadratic Form Distance between the reference signature and each of the other image signatures.

Parameters
  • sourceSignature: The signature to measure distance of other signatures from.
  • imageSignatures: Vector of signatures to measure distance from the source signature.
  • distances: Output vector of measured distances.
