# trackerNmsIouThreshold property

int trackerNmsIouThreshold

Non-maximum suppression (NMS) intersection-over-union (IOU) threshold, in the range `0;100`. Hint: Default value is 0. 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.

throws FaceException An error has occurred during Face Library execution.

## Implementation

    int get trackerNmsIouThreshold => getTrackerNmsIouThreshold();

void trackerNmsIouThreshold=(int value)

## Implementation

    set trackerNmsIouThreshold(int value) => setTrackerNmsIouThreshold(value);
