MPPImageClassifierLiveStreamDelegate
@protocol MPPImageClassifierLiveStreamDelegate < NSObject >
This protocol defines an interface for the delegates of ImageClassifier
object to receive
results of asynchronous classification of images (i.e, when runningMode
= .liveStream
).
The delegate of ImageClassifier
must adopt ImageClassifierLiveStreamDelegate
protocol.
The methods in this protocol are optional.
This method notifies a delegate that the results of asynchronous classification of
an image submitted to the ImageClassifier
is available.
This method is called on a private serial queue created by the ImageClassifier
for performing the asynchronous delegates calls.
Declaration
Objective-C
- ( void ) imageClassifier :( nonnull MPPImageClassifier * ) imageClassifier
didFinishClassificationWithResult :
( nullable MPPImageClassifierResult * ) result
timestampInMilliseconds :( NSInteger ) timestampInMilliseconds
error :( nullable NSError * ) error ;
Parameters
imageClassifier
The image classifier which performed the classification.
This is useful to test equality when there are multiple instances of ImageClassifier
.
result
An ImageClassifierResult
object that contains a list of image classifications.
timestampInMilliseconds
The timestamp (in milliseconds) which indicates when the input
image was sent to the image classifier.
error
An optional error parameter populated when there is an error in performing image
classification on the input live stream image data.
