# compareTemplates method

int compareTemplates(

1. FaceTemplate reference,
2. FaceTemplate probe

)

Compares two templates and outputs a comparison score.

param reference Reference template. param probe Probe template. return The comparison score, in the range (0;65535). throws FaceException An error has occurred during Face Library execution.

## Implementation

    int compareTemplates(FaceTemplate reference, FaceTemplate probe) {
      Pointer<Int> pScore = calloc();
      try {
        var err = faceSDK.id3FaceMatcher_CompareTemplates(_pHandle.value, reference.handle, probe.handle, pScore);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vScore = pScore.value;
        return vScore;
      } finally {
        calloc.free(pScore);
      }
    }
