<h1>What is OpenCV</h1>
|
||
|
|
|
||
|
|
<p>OpenCV means Open Source Computer Vision Library.
|
||
|
|
It is a collection of C functions and a few C++ classes that implement
|
||
|
|
many popular Image Processing and Computer Vision algorithms.</p>

<h1>The key features</h1>
|
||
|
|
|
||
|
|
<p>OpenCV provides cross-platform middle-to-high level API that includes
|
||
|
|
about 300 functions and a few C++ classes. Also there are
|
||
|
|
constantly improving Python bindings to OpenCV, see
|
||
|
|
interfaces/swig/python and samples/python.
|
||
|
|
OpenCV has no strict dependencies on external libraries,
|
||
|
|
though it can use some (such as libjpeg, ffmpeg, GTK+ etc.)
|
||
|
|
when it is possible.</p>
|
||
|
|
|
||
|
|
<p>OpenCV is free for both non-commercial and commercial use
|
||
|
|
(see the <a href="license.txt">license</a> for details).</p>
|
||
|
|
|
||
|
|
<p><a name="#ipp">OpenCV can be built with Intel® Integrated Performance
|
||
|
|
Primitives (IPP).</a>
|
||
|
|
This makes it fast on all the architectures supported by the library,
|
||
|
|
where the optimal code for each host architecture is chosen at runtime.
|
||
|
|
|
||
|
|
More information about IPP can be retrieved at

||

|

|
||
|
|
|
||
|
|
Then, OpenCV itself can be built with <a href="http://www.threadingbuildingblocks.org/">TBB</a>
|
||
|
|
support, and, starting with v2.0,
|
||
|
|
OpenCV also includes SSE2-optimized code, so many of the functions run significantly
|
||
|
|
faster on the modern 32-bit x86 and 64-bit x64 platforms, and even faster on dual-,
|
||
|
|
quad- and many-core systems.

<ol>
|
||
|
|
<li>Visit OpenCV Wiki-pages at
|
||
|
|
<a href="http://opencv.willowgarage.com/wiki/">http://opencv.willowgarage.com/wiki/</a> and
|
||
|
|
look for the information there (and/or add it when you have found a solution)
|
||
|
|
<li>Search through OpenCV archives at www.yahoogroups.com
|
||
|
|
(<a href="http://groups.yahoo.com/group/OpenCV/">http://groups.yahoo.com/group/OpenCV/</a>)
|
||
|
|
<li>Join OpenCV mailing list at yahoo groups (see FAQs on how to do it) and mail your questions
|
||
|
|
(the mailing list will probably migrate to
|
||
|
|
<a href="http://www.sourceforge.net/projects/opencvlibrary">OpenCV's SourceForge site</a>)
|
||
|
|
<li>Look at the OpenCV sample code, read the reference manual <a href="opencv.pdf">offline in PDF</a>
|
||
|
|
or online (<a href="http://opencv.willowgarage.com/documentation/c/index.html">C</a>,
