<h1 class="title">Intel® Threading Building Blocks.<br>Stereo sample</h1>
</div>
<p>
The Stereo example is an implementation of the algorithm that applies stereoscopic 3D effect on two input images and achieved by means of encoding each eye's image using filters of different colors: red and blue -
<a href="http://en.wikipedia.org/wiki/Anaglyph_3D"><i>Anaglyph effect</i></a>.
<br><br>
The example uses the flow graph interface and can be executed both on CPU and GPU for image processing.
The output of this application is a PNG image with the anaglyph effect applied.
<br><br>
<i>
This example includes software developed by Lode Vandevenne. See
<a href="#copyright">here</a> for copyright information.
</i>
<br>
It exemplifies the opencl_node usage in the flow graph interface in context of creating a stereo image from two input images.
<br><br>
This example uses C++11 lambda expressions. Specifying a compiler option such as -std=c++11 or similar might be necessary in order to build the example.
For more information please refer to the documentation for the compiler you use.
