public Sam2Translator()

Constructs a Sam2Translator instance.

Method Details

processInput

public NDList processInput(TranslatorContext ctx,
 Sam2Translator.Sam2Input input)
                    throws Exception

Processes the input and converts it to NDList.

Specified by:

processInput in interface PreProcessor<Sam2Translator.Sam2Input>

Parameters:

ctx - the toolkit for creating the input NDArray

input - the input object

Returns:

the NDList after pre-processing

Throws:

Exception - if an error occurs during processing input

processOutput

public DetectedObjects processOutput(TranslatorContext ctx,
 NDList list)
                              throws Exception

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, usually immutable in engines like PyTorch. @see Issue 1774

Returns:

the output object of expected type

Throws:

Exception - if an error occurs during processing output
