Constructor Detail

InstanceSegmentationTranslator

public InstanceSegmentationTranslator(InstanceSegmentationTranslator.Builder builder)

Creates the Instance Segmentation translator from the given builder.

Parameters:

builder - the builder for the translator

Method Detail

transform

public NDArray transform(NDArray array)

Applies the Transform to the given NDArray.

Specified by:

transform in interface Transform

Parameters:

array - the NDArray on which the Transform is applied

Returns:

the output of the Transform

prepare

public void prepare(NDManager manager,
                    Model model)
             throws java.io.IOException

Prepares the translator with the manager and model to use.

Specified by:

prepare in interface Translator<Image,DetectedObjects>

Parameters:

manager - the manager for the translator

model - the model to translate for

Throws:

java.io.IOException - if there is an error reading inputs for preparing the translator

processInput

public NDList processInput(TranslatorContext ctx,
                           Image image)

Processes the Image input and converts it to NDList.

Specified by:

processInput in interface PreProcessor<Image>

Overrides:

processInput in class BaseImageTranslator<DetectedObjects>

Parameters:

ctx - the toolkit that helps create the input NDArray

image - the Image input

Returns:

a NDList

processOutput

public DetectedObjects processOutput(TranslatorContext ctx,
                                     NDList list)

Processes the output NDList to the corresponding output object.

Specified by:

processOutput in interface PostProcessor<DetectedObjects>

Parameters:

ctx - the toolkit used for post-processing

list - the output NDList after inference

Returns:

the output object of expected type

builder
