# DetectDocumentSegmentationRequest

A request that detects rectangular regions that contain text in the input image.

## Declaration

```swift
struct DetectDocumentSegmentationRequest
```

## Overview

Overview Perform this request to detect a document in an image. The result that the request generates contains the four corner points of a document’s quadrilateral and saliency masks. The request returns the resulting location and segmentation mask in an instance of DetectedDocumentObservation.
