+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.

Explanation
===========
and IPP Async:
.. code-block:: cpp
-
- Ptr<hppiMatrix> src, dst;
+
+ 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");
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
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);
+ src = getHpp(gray, accel);
+ dst = getHpp(result, accel);
sts = hppiSobel(accel,src, HPP_MASK_SIZE_3X3,HPP_NORM_L1,virtMatrix[0]);
CHECK_STATUS(sts,"hppiSobel");
// 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.
imshow("rez", result);
waitKey(15);
-
+
+#. Delete hpp matrices.
+
+ .. code-block:: cpp
+
+ sts = hppiFreeMatrix(src);
+ CHECK_DEL_STATUS(sts,"hppiFreeMatrix");
+
+ sts = hppiFreeMatrix(dst);
+ CHECK_DEL_STATUS(sts,"hppiFreeMatrix");
+
#. Delete virtual matrices and accelerator instance.
.. code-block:: cpp
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.

+ + |IntelIIPA|_ is currently focused delivering Intel |copy| Graphics support for advanced image processing and computer vision functions.
+
+ OpenCV offers a somewhat fancier and more useful graphical user interface, than the default one by using the |qtframework|_. For a quick overview of what this has to offer look into the documentations *highgui* module, under the *Qt New Functions* section. Version 4.6 or later of the framework is required.
+ |Eigen|_ is a C++ template library for linear algebra.
:alt: The Miktex Install Screen
:align: center
+ #) For the |IntelIIPA|_ download the source files and set environment variable **IPP_ASYNC_ROOT**. It should point to :file:`<your Program Files(x86) directory>/Intel/IPP Preview */ipp directory`. Here ``*`` denotes the particular preview name.
+
#) In case of the |Eigen|_ library it is again a case of download and extract to the :file:`D:/OpenCV/dep` directory.
#) Same as above with |OpenEXR|_.
