# inputFaceObservations

An array of face-observation objects to process as part of the request.

```
var inputFaceObservations: [FaceObservation]?
```

## Discussion

The default is `nil`. When `nil`, the framework first performs a [`DetectFaceRectanglesRequest`](/documentation/Vision/DetectFaceRectanglesRequest) and processes all faces detected.
