       <parser class="org.apache.tika.parser.recognition.ObjectRecognitionParser">
        <params>
          <param name="class" type="string">org.apache.tika.parser.recognition.tf.TensorflowRESTRecogniser</param>
          <param name="class" type="string">org.apache.tika.parser.captioning.tf.TensorflowRESTCaptioner</param>
        </params>
       </parser>

        public void parse​(InputStream stream,
                          ContentHandler handler,
                          Metadata metadata,

                          TikaException
        Description copied from interface: Parser
        Parses a document stream into a sequence of XHTML SAX events. Fills in related document metadata in the given metadata object.

        The given document stream is consumed but not closed by this method. The responsibility to close the stream remains on the caller.

        Information about the parsing context can be passed in the context parameter. See the parser implementations for the kinds of context information they expect.

        Specified by:
        parse in interface Parser
        Parameters:
        stream - the document stream (input)
        handler - handler for the XHTML SAX events (output)
        metadata - document metadata (input and output)
        context - parse context
        Throws:
        IOException - if the document stream could not be read
        SAXException - if the SAX events could not be processed
        TikaException - if the document could not be parsed
