Declaration
protected ~InferenceImageClassifier()
View Source

GetRequestResults()

Gets the labels as a result of RequestInference(MediaVisionSource).

Declaration
public InferenceImageClassifierResult GetRequestResults()
Returns
Type Description
InferenceImageClassifierResult

The labels of classified image.
Remarks

If image is not classified, Labels will be empty.
This method uses about twice as much memory as Inference(MediaVisionSource).

Exceptions

Inference(MediaVisionSource)

Classifies image synchronously.

Declaration
public InferenceImageClassifierResult Inference(MediaVisionSource source)
Parameters
Type Name Description
MediaVisionSource source

The image data to classify.
Returns
Type Description
InferenceImageClassifierResult

The labels of classified image.
Remarks

Labels can be empty, if image is not classified.

Exceptions
Type Condition
System.ObjectDisposedException

The InferenceImageClassifier already has been disposed.
System.ArgumentNullException

source is null.

InferenceAsync(MediaVisionSource)

Classifies image asynchronously.

Declaration
public Task<InferenceImageClassifierResult> InferenceAsync(MediaVisionSource source)
Parameters
Type Name Description
MediaVisionSource source

The image data to classify.
Returns
Type Description
System.Threading.Tasks.Task<TResult><InferenceImageClassifierResult>
Remarks

Labels can be empty, if image is not classified.
This method uses about twice as much memory as Inference(MediaVisionSource).

Exceptions
Type Condition
System.ObjectDisposedException

The InferenceImageClassifier already has been disposed.
System.ArgumentNullException

source is null.
View Source

RequestInference(MediaVisionSource)

Requests classifing image to get its labels asynchronously.

Declaration
public ulong RequestInference(MediaVisionSource source)
Parameters
Type Name Description
MediaVisionSource source

The image data to classify.
Returns
Type Description
ulong

The request ID that indicates the order of requests.
Remarks

This function does not guarantee that inference is done when this method returns. The user can get the result by using GetRequestResults().
If the user calls this method again before the previous one is finished internally, the call will be ignored.
Labels can be empty, if image is not classified.
Note that this method could use about twice as much memory as Inference(MediaVisionSource).

Exceptions
Type Condition
System.ObjectDisposedException

The InferenceImageClassifier already has been disposed.
