# VNFaceObservation

Face or facial-feature information that an image analysis request detects.

## Declaration

```swift
class VNFaceObservation
```

## Overview

Overview This type of observation results from a VNDetectFaceRectanglesRequest. It contains information about facial landmarks and regions it finds in the image.

## Topics

### Creating an Observation
