This protocol defines an interface for the delegates of ObjectDetector object to receive
results of performing asynchronous object detection on images (i.e, when runningMode =
.liveStream).
The delegate of ObjectDetector must adopt ObjectDetectorLiveStreamDelegate protocol.
The methods in this protocol are optional.
The object detector which performed the object detection.
This is useful to test equality when there are multiple instances of ObjectDetector.
result
The ObjectDetectorResult object that contains a list of detections, each
detection has a bounding box that is expressed in the unrotated input frame of reference
coordinates system, i.e. in [0,image_width) x [0,image_height), which are the dimensions of the
underlying image data.
timestampInMilliseconds
The timestamp (in milliseconds) which indicates when the input
image was sent to the object detector.
error
An optional error parameter populated when there is an error in performing object
detection on the input live stream image data.
