# MPSGraphNonMaximumSuppressionCoordinateMode

The non-maximum suppression coordinate mode.

## Declaration

```swift
enum MPSGraphNonMaximumSuppressionCoordinateMode
```

## Overview

Overview The coordinate mode to use. At initialization defaults to MPSGraphNonMaximumSuppressionCoordinateModeCornersHeightFirst. This mode specifies the representation used for the 4 box coordinate values. Center coordinate modes define a centered box and the box dimensions. CornersHeightFirst:     [h_start, w_start, h_end, w_end] CornersWidthFirst:     [w_start, h_start, w_end, h_end] CentersHeightFirst:     [h_center, w_center, box_height, box_width] CentersWidthFirst:     [w_center, w_center, box_height, box_width]
