Options for setting up a ImageEmbedder
.
-
Running mode of the image embedder task. Defaults to
.image.ImageEmbeddercan be created with one of the following running modes:-
.image: The mode for performing embedding extraction on single image inputs. -
.video: The mode for performing embedding extraction on the decoded frames of a video. -
.liveStream: The mode for performing embedding extraction on a live stream of input data, such as from the camera.
Declaration
Objective-C
@property ( nonatomic ) MPPRunningMode runningMode ; -
-
An object that confirms to
ImageEmbedderLiveStreamDelegateprotocol. This object must implementimageEmbedder(_:didFinishEmbeddingWithResult:timestampInMilliseconds:error:)to receive the results of asynchronous embedding extraction on images (i.e, whenrunningMode = .liveStream).Declaration
Objective-C
@property ( nonatomic , weak , nullable ) id < MPPImageEmbedderLiveStreamDelegate > imageEmbedderLiveStreamDelegate ; -
@brief Sets whether L2 normalization should be performed on the returned embeddings. Use this option only if the model does not already contain a native L2_NORMALIZATION TF Lite Op. In most cases, this is already the case and L2 norm is thus achieved through TF Lite inference.
NOby default.Declaration
Objective-C
@property ( nonatomic ) BOOL l2Normalize ; -
@brief Sets whether the returned embedding should be quantized to bytes via scalar quantization. Embeddings are implicitly assumed to be unit-norm and therefore any dimensions is guaranteed to have value in [-1.0, 1.0]. Use the
l2Normalizeproperty if this is not the case.NOby default.Declaration
Objective-C
@property ( nonatomic ) BOOL quantize ;
