+
+Intel® IPP Asynchronous C/C++ library in OpenCV
+***********************************************
+
+Goal
+====
+
+.. _hppiSobel: http://software.intel.com/en-us/node/474701
+.. _hppiMatrix: http://software.intel.com/en-us/node/501660
+
+The tutorial demonstrates the `Intel® IPP Asynchronous C/C++ <http://software.intel.com/en-us/intel-ipp-preview>`_ library usage with OpenCV. 
+The code example below illustrates implementation of the Sobel operation, accelerated with Intel® IPP Asynchronous C/C++ functions.
+In this code example, :ippa_convert:`hpp::getMat <>` and :ippa_convert:`hpp::getHpp <>` functions are used for data conversion between hppiMatrix_ and ``Mat`` matrices.
+
+Code
+====
+
+You may also find the source code in the :file:`samples/cpp/tutorial_code/core/ippasync/ippasync_sample.cpp` 
+file of the OpenCV source library or :download:`download it from here
+<../../../../samples/cpp/tutorial_code/core/ippasync/ippasync_sample.cpp>`.

+.. literalinclude:: ../../../../samples/cpp/tutorial_code/core/ippasync/ippasync_sample.cpp
+   :language: cpp
+   :linenos:
+   :tab-width: 4
+   
+Explanation
+===========
+
+#. Create parameters for OpenCV:
+
+   .. code-block:: cpp
+
+      VideoCapture cap;
+      Mat image, gray, result;
+
+   and IPP Async:
+
+   .. code-block:: cpp
+   
+      Ptr<hppiMatrix> src, dst;
+      hppAccel accel = 0;
+      hppAccelType accelType;
+      hppStatus sts;
+      hppiVirtualMatrix * virtMatrix;
+
+#. Load input image or video. How to open and read video stream you can see in the :ref:`videoInputPSNRMSSIM` tutorial.
+   
+   .. code-block:: cpp
+   
+      if( useCamera )
+      {
+         printf("used camera\n");
+         cap.open(0);
+      }
+      else
+      {
+         printf("used image %s\n", file.c_str());
+         cap.open(file.c_str());
+      }
+
+      if( !cap.isOpened() )
+      {
+         printf("can not open camera or video file\n");
+         return -1;
+      }
+   
+#. Create accelerator instance using `hppCreateInstance <http://software.intel.com/en-us/node/501686>`_:
+
+   .. code-block:: cpp
+   
+      accelType = sAccel == "cpu" ? HPP_ACCEL_TYPE_CPU:
+                  sAccel == "gpu" ? HPP_ACCEL_TYPE_GPU:
+                                    HPP_ACCEL_TYPE_ANY;
+                                    
+      //Create accelerator instance
+      sts = hppCreateInstance(accelType, 0, &accel);
+      CHECK_STATUS(sts, "hppCreateInstance");
+   
+#. Create an array of virtual matrices using `hppiCreateVirtualMatrices <http://software.intel.com/en-us/node/501700>`_ function.
+
+   .. code-block:: cpp
+
+      virtMatrix = hppiCreateVirtualMatrices(accel, 1);
+   
+#. Prepare a matrix for input and output data:
+
+   .. code-block:: cpp
+
+      cap >> image;
+      if(image.empty())
+         break;
+
+      cvtColor( image, gray, COLOR_BGR2GRAY );
+
+      result.create( image.rows, image.cols, CV_8U);
+   
+#. Convert ``Mat`` to hppiMatrix_ using :ippa_convert:`getHpp <>` and call hppiSobel_ function.
+
+   .. code-block:: cpp
+
+      //convert Mat to hppiMatrix
+      src = getHpp(gray);
+      dst = getHpp(result);
+
+      sts = hppiSobel(accel,src, HPP_MASK_SIZE_3X3,HPP_NORM_L1,virtMatrix[0]);
+      CHECK_STATUS(sts,"hppiSobel");
+
+      sts = hppiConvert(accel, virtMatrix[0], 0, HPP_RND_MODE_NEAR, dst, HPP_DATA_TYPE_8U);
+      CHECK_STATUS(sts,"hppiConvert");
+
+      // Wait for tasks to complete
+      sts = hppWait(accel, HPP_TIME_OUT_INFINITE);
+      CHECK_STATUS(sts, "hppWait");
+   
+   We use `hppiConvert <http://software.intel.com/en-us/node/501746>`_ because hppiSobel_ returns destination
+   matrix with ``HPP_DATA_TYPE_16S`` data type for source matrix with ``HPP_DATA_TYPE_8U`` type.
+   You should check ``hppStatus`` after each call IPP Async function.
+
+#. Create windows and show the images, the usual way.
+
+   .. code-block:: cpp
+
+      imshow("image", image);
+      imshow("rez", result);
+
+      waitKey(15);
+   
+#. Delete virtual matrices and accelerator instance.
+
+   .. code-block:: cpp
+
+      if (virtMatrix)
+      {
+         sts = hppiDeleteVirtualMatrices(accel, virtMatrix);
+         CHECK_DEL_STATUS(sts,"hppiDeleteVirtualMatrices");
+      }
+
+      if (accel)
+      {
+         sts = hppDeleteInstance(accel);
+         CHECK_DEL_STATUS(sts, "hppDeleteInstance");
+      }
+
+   We shouldn't delete hppiMatrix_ because we use :ptr:`Ptr <>` and so `hppiFreeMatrix <http://software.intel.com/en-us/node/501699>`_ will be called implicitly.
+
+Result
+=======
+
+After compiling the code above we can execute it giving an image or video path and accelerator type as an argument. 
+For this tutorial we use baboon.png image as input. The result is below.
