# TrackTranslationalImageRegistrationRequest

An image-analysis request that you track over time to determine the affine transform necessary to align the content of two images.

## Declaration

```swift
final class TrackTranslationalImageRegistrationRequest
```

## Overview

Overview This request generates an ImageTranslationAlignmentObservation object that describes the transform data the request detects.
