Class VNRectangleObservation

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject, VNRequestRevisionProviding
    Direct Known Subclasses:
    VNBarcodeObservation, VNRecognizedTextObservation, VNTextObservation

    public class VNRectangleObservation
    extends VNDetectedObjectObservation
    VNRectangleObservation [@superclass] VNDetectedObjectObservation VNRectangleObservation is the result of a rectangle detector The VNRectangleObservation has a bounding box that encompasses the rectangle found in the image. The rectangle itself is defined by the four corner point properties. The rectangle can be rotated in or even out of plane. A common use case is to use the CIPerspectiveTransform filter to correct a detected rectangle to its 'flat upright' representation. All coordinates are normalized and the coordinates can be outside the image. API-Since: 11.0

        Create a synthesized `VNRectangleObservation`. [@note] The clockwise parameter ordered `+[VNRectangleObservation rectangleObservationWithRequestRevision:topLeft:topRight:bottomRight:bottomLeft:]` is the preferred initializer.
        Parameters:
        requestRevision - The revision of the VNDetectRectanglesRequest that the observation is to be treated as originating from.
        topLeft - The top-left corner of the rectangle in normalized coordinate space.
        bottomLeft - The bottom-left corner of the rectangle in normalized coordinate space.
        bottomRight - The bottom-right corner of the rectangle in normalized coordinate space.
        topRight - The top-right corner of the rectangle in normalized coordinate space. API-Since: 13.0 Deprecated-Since: 17.0
