MLKCustomObjectDetectorOptions


@interface MLKCustomObjectDetectorOptions : MLKCommonObjectDetectorOptions

Configurations for a custom-model object detector.

  • The confidence threshold for labels returned by the object detector. Labels returned by the object detector will have a confidence level higher or equal to the given threshold. The threshold is a floating-point value and must be in range [0, 1]. If unset or an invalid value is set, any classifier threshold specified by the model’s metadata will be used. If the model does not contain any metadata or the metadata does not specify a classifier threshold, the default threshold of 0.0 is used.

    Declaration

    Objective-C

    @property (nonatomic, nullable) NSNumber *classificationConfidenceThreshold;

  • The maximum number of labels to return for a detected object. Must be positive. If unset or an invalid value is set, the default value of 10 is used.

    Declaration

    Objective-C

    @property (nonatomic) NSInteger maxPerObjectLabelCount;

  • Initializes a CustomObjectDetectorOptions instance using the given LocalModel with the classificationConfidenceThreshold property set to nil. If that remains unset, it will use the confidence threshold value included in the model metadata, if available. If that does not exist, a value of 0.0 will be used instead.

    Declaration

    Objective-C

    - (nonnull instancetype)initWithLocalModel:(nonnull MLKLocalModel *)localModel;

    Parameters

    localModel

    A custom object classification model stored locally on the device.

    Return Value

    A new instance of CustomObjectDetectorOptions with the given LocalModel.

  • Initializes a CustomObjectDetectorOptions instance using the given CustomRemoteModel with the classificationConfidenceThreshold property set to nil. If that remains unset, it will use the confidence threshold value included in the model metadata, if available. If that does not exist, a value of 0.0 will be used instead.

    Declaration

    Objective-C

    - (nonnull instancetype)initWithRemoteModel:
    (nonnull MLKCustomRemoteModel *)remoteModel;

    Parameters

    remoteModel

    A custom object classification model stored remotely on the server and downloaded to the device.

    Return Value

    A new instance of CustomObjectDetectorOptions with the given CustomRemoteModel.

  • Unavailable.

    Declaration

    Objective-C

    - (nonnull instancetype)init;
