ImageSegmenterLiveStreamDelegate
protocol ImageSegmenterLiveStreamDelegate : NSObjectProtocol
This protocol defines an interface for the delegates of ImageSegmenter
object to receive
results of performing asynchronous segmentation on images (i.e, when runningMode
=
liveStream
).
The delegate of ImageSegmenter
must adopt ImageSegmenterLiveStreamDelegate
protocol.
The methods in this protocol are optional.
This method notifies a delegate that the results of asynchronous segmentation of
an image submitted to the ImageSegmenter
is available.
This method is called on a private serial dispatch queue created by the ImageSegmenter
for performing the asynchronous delegates calls.
Declaration
Swift
optional func imageSegmenter ( _ imageSegmenter : MPPImageSegmenter , didFinishSegmentation result : ImageSegmenterResult ?, timestampInMilliseconds : Int , error : Error ?)
Parameters
imageSegmenter
The image segmenter which performed the segmentation. This is useful to
test equality when there are multiple instances of ImageSegmenter
.
result
The ImageSegmenterResult
object that contains a list of category or confidence
masks and optional quality scores.
timestampInMilliseconds
The timestamp (in milliseconds) which indicates when the input
image was sent to the image segmenter.
error
An optional error parameter populated when there is an error in performing
segmentation on the input live stream image data.
