A request to classify an image.


class VNClassifyImageRequest : VNImageBasedRequest


This type of request produces a collection of VNClassificationObservation objects that describe an image. Access the classifications through knownClassifications(forRevision:).

class func knownClassifications(forRevision: Int) -> [VNClassificationObservation]

Requests the collection of classifications that the Vision framework recognizes.

class VNClassificationObservation

Classification information produced by an image analysis request.

Specifying Algorithm Revision

let VNClassifyImageRequestRevision1: Int

A constant for specifying revision 1 of the image classification algorithm.
