    ImageClassifierOptions

      class 
 ImageClassifierOptions 
 : 
  TaskOptions 
 
 , 
 NSCopying

    Options for setting up a ImageClassifier .

    • Running mode of the image classifier task. Defaults to .image . ImageClassifier can be created with one of the following running modes:

      1. .image : The mode for performing classification on single image inputs.
      2. .video : The mode for performing classification on the decoded frames of a video.
      3. .liveStream : The mode for performing classification on a live stream of input data, such as from the camera.

      Declaration

      Swift

        var 
 runningMode 
 : 
  RunningMode 
 
 { 
 get 
 set 
 }

    • An object that confirms to ImageClassifierLiveStreamDelegate protocol. This object must implement objectDetector(_:didFinishDetectionWithResult:timestampInMilliseconds:error:) to receive the results of asynchronous classification on images (i.e, when runningMode = .liveStream ).

      Declaration

      Swift

        weak 
 var 
 imageClassifierLiveStreamDelegate 
 : 
  ImageClassifierLiveStreamDelegate 
 
 ? 
 { 
 get 
 set 
 }

    • The locale to use for display names specified through the TFLite Model Metadata, if any. Defaults to English.

      Declaration

      Swift

        var 
 displayNamesLocale 
 : 
 String 
 { 
 get 
 set 
 }

    • The maximum number of top-scored classification results to return. If < 0, all available results will be returned. If 0, an invalid argument error is returned.

      Declaration

      Swift

        var 
 maxResults 
 : 
 Int 
 { 
 get 
 set 
 }

    • Score threshold to override the one provided in the model metadata (if any). Results below this value are rejected.

      Declaration

      Swift

        var 
 scoreThreshold 
 : 
 Float 
 { 
 get 
 set 
 }

    • The allowlist of category names. If non-empty, detection results whose category name is not in this set will be filtered out. Duplicate or unknown category names are ignored. Mutually exclusive with categoryDenylist.

      Declaration

      Swift

        var 
 categoryAllowlist 
 : 
 [ 
 String 
 ] 
 { 
 get 
 set 
 }

    • The denylist of category names. If non-empty, detection results whose category name is in this set will be filtered out. Duplicate or unknown category names are ignored. Mutually exclusive with categoryAllowlist.

      Declaration

      Swift

        var 
 categoryDenylist 
 : 
 [ 
 String 
 ] 
 { 
 get 
 set 
 }
