getNmsIouThreshold method

int getNmsIouThreshold()

Gets the non-maximum suppression (NMS) intersection-over-union (IOU) threshold, in the range is (0;100). Hint: Default value is 40. Setting a high threshold allows to detect more overlapping faces which can be useful in a multi-face scenario. On the contrary, in a portrait scenario, a low NMS IOU threshold should be preferred.

return Non-maximum suppression (NMS) intersection-over-union (IOU) threshold, in the range is (0;100). throws FaceException An error has occurred during Face Library execution.

Implementation

int getNmsIouThreshold() {
  Pointer<Int> pNmsIouThreshold = calloc();
  try {
    var err = faceSDK.id3FaceTracker_GetNmsIouThreshold(_pHandle.value, pNmsIouThreshold);
    if (err != FaceError.success.value) {
      throw FaceException(err);
    }
    final vNmsIouThreshold = pNmsIouThreshold.value;
    return vNmsIouThreshold;
  } finally {
    calloc.free(pNmsIouThreshold);
  }
}
