struct · iOS 18.0+ · SDK 27.1

struct DetectDocumentSegmentationRequest

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

Swift declaration
var descriptor: RequestDescriptor { get }

An enum that identifies the request and request revision.

regionOfInterest

TypeScript
get regionOfInterest(): NormalizedRect
Swift declaration
var regionOfInterest: NormalizedRect

The region of the image in which Vision will perform the request. The rectangle is normalized to the dimensions of the processed image. Its origin is specified relative to the image's lower-left corner. By default, the region of interest will be the full image.

regionOfInterest

TypeScript
set regionOfInterest(value: NormalizedRect)
Swift declaration
var regionOfInterest: NormalizedRect

The region of the image in which Vision will perform the request. The rectangle is normalized to the dimensions of the processed image. Its origin is specified relative to the image's lower-left corner. By default, the region of interest will be the full image.

setComputeDevice

TypeScript
setComputeDevice(computeDevice: (_CoreML_MLComputeDevice) | null, computeStage: ComputeStage): void
Swift declaration
mutating func setComputeDevice(_ computeDevice: MLComputeDevice?, for computeStage: ComputeStage)

Assigns a compute device for a compute stage. If the parameter `computeDevice` is `nil`, the framework removes any explicit compute device assignment and allows the framework to select the device. Configure any compute device for a given compute stage. When performing a request, the system makes a validity check. Use `supportedComputeStageDevices` to get valid compute devices for a request’s compute stages. - Parameters: - `computeDevice: `The compute device to assign to the compute stage. - `computeStage: `The compute stage.
