Yes

OS Platform and Distribution

Task name (e.g. Image classification, Gesture recognition etc.)

hand recongnistion

Programming Language and version (e.g. C++, Python, Java)

C++

Describe the actual behavior

Standalone code/steps you may have used to try to get what you need

// Wrap Mat into an ImageFrame.
	auto input_frame = absl::make_unique<mediapipe::ImageFrame>(
		mediapipe::ImageFormat::SRGB, camera_frame_RGB.cols, camera_frame_RGB.rows,
		mediapipe::ImageFrame::kDefaultAlignmentBoundary);

	camera_frame_RGB.copyTo(mediapipe::formats::MatView(input_frame.get()));

	//std::cout << "Wrap Mat into an ImageFrame." << std::endl;

	// Send image packet into the graph.
	size_t frame_timestamp_us =
		(double)cv::getTickCount() / (double)cv::getTickFrequency() * 1e6;

	MP_RETURN_IF_ERROR(m_Graph.AddPacketToInputStream(
		m_kInputStream, mediapipe::Adopt(input_frame.release())
		.At(mediapipe::Timestamp(frame_timestamp_us))));
	//std::cout << "Send image packet into the graph." << std::endl;


	// Get the graph result packet, or stop if that fails.
	mediapipe::Packet packet;
	mediapipe::Packet packet_landmarks;
	if (!m_pPoller->Next(&packet))
		return absl::OkStatus();

	if (m_pPoller_landmarks->QueueSize() > 0)
	{
		if (m_pPoller_landmarks->Next(&packet_landmarks))
		{

			std::vector<mediapipe::NormalizedLandmarkList> output_landmarks = packet_landmarks.Get<std::vector<mediapipe::NormalizedLandmarkList>>();
			//GestureRecognitionResult tempGestureResult;
			//auto handness= output_landmarks[0].classification().label();
			for (int m = 0; m < output_landmarks.size(); ++m)
			{
				mediapipe::NormalizedLandmarkList single_hand_NormalizedLandmarkList = output_landmarks[m];
				//single_hand_NormalizedLandmarkList.mutable_landmark()
				std::vector<PoseInfo> singleHandGestureInfo;
				singleHandGestureInfo.clear();
				for (int i = 0; i < single_hand_NormalizedLandmarkList.landmark_size(); ++i)
				{
					PoseInfo info;
					const mediapipe::NormalizedLandmark landmark = single_hand_NormalizedLandmarkList.landmark(i);
					info.x = landmark.x() * camera_frame.cols;
					info.y = landmark.y() * camera_frame.rows;
					singleHandGestureInfo.push_back(info);
				}
}
