Constructor Details

SingleShotDetectionTranslator

public SingleShotDetectionTranslator(SingleShotDetectionTranslator.Builder builder)

Creates the SSD translator from the given builder.

Parameters:

builder - the builder for the translator

Method Details

processOutput

public DetectedObjects processOutput(TranslatorContext ctx,
 NDList list)

Processes the output NDList to the corresponding output object.

Parameters:

ctx - the toolkit used for post-processing

list - the output NDList after inference, usually immutable in engines like PyTorch. @see Issue 1774

Returns:

the output object of expected type

builder

public static SingleShotDetectionTranslator.Builder builder()

Creates a builder to build a SingleShotDetectionTranslator.

Returns:

a new builder

builder

public static SingleShotDetectionTranslator.Builder builder(Map<String,?> arguments)

Creates a builder to build a SingleShotDetectionTranslator with specified arguments.

Parameters:

arguments - arguments to specify builder options

Returns:

a new builder
