# CIFaceFeature

Information about a face detected in a still or video image.

## Declaration

```swift
class CIFaceFeature
```

## Overview

Overview note: In macOS 10.13, iOS 11, and tvOS 11 or later, the Vision framework replaces this class for identifying and analyzing image features. See VNDetectFaceRectanglesRequest. See VNDetectFaceRectanglesRequest) The properties of a CIFaceFeature object provide information about the face’s eyes and mouth. A face object in a video can also have properties that track its location over time, tracking ID and frame count.
