-
-This is a community effort, code and algorithm contribution of new and
-existing algorithms are encouraged. The library targets 3 areas of use.</p>
-
- <ul>
- <li>Commercial: Performance optimized code for use in commercial applications that are free for use, modification and redistribution (subject to the license);</li>
- <li>Research: A common substrate for disseminating new work that, in addition, is largely optimized;</li>
- <li>Tutorial: Documented code and algorithms intended to be used for teaching.</li>
- </ul>
- <p align="left">There are more than 300 functions in OpenCV that are tuned
- for faster execution on the latest Intel processors. Significant part of the
- library is optimized using MMX and SSE instructions.</p>
- <p align="left">The library performance and functionality are improving
- quickly.</p>
- <p align="left">Read the <a href="../../History.txt">history</a> file for change history.
- The OpenCV API has changed. See the list of changes <a href="../../interface_changes.txt">here</a>. </p>

- Installation
- </h2>
- <h3>
-
- Under Win32:
- </h3>
- <p>
-
- The whole OpenCV delivery is broken up into several smaller packages:
- </p>
- <ul>
- <li>The core: CV and helper libraries sources and binaries, documentation
- (opencv_core_b1.zip)</li>
- <li>Demo appplications, DirectShow filters, scripting environment, tests
- for the library (opencv_apps_b1.zip). The package depends on the core
- package.</li>
- <li>Calibration toolbox for MATLAB (opencv_calib_toolbox.zip).</li>
- </ul>
- <p>
-
- To install each package download it, uncompress and run setup.exe
- </p>
- <h3>
-
- Under Linux:
- </h3>
- <p>There is a single package for Linux: opencv-linux-b1.tar.gz. The package
- content is the same as opencv_core_b1.zip, but additionally includes demo
- application VMDemo.
- </p>
- <p>To install it, do the following steps:
- </p>
- <ol>
- <li>To install the libraries, type:<br>
- ./configure<br>
- make<br>
- make install # as root<br>
- ldconfig # as root<br>
- </li>
- <li>
- <p style="line-height: 100%; margin-top: 0; margin-bottom: 0">To run
- demo application VMDemo, you should have TCL/TK 8.3.x and "Img image format extension"
- widget installed.<br>
- (visit <a href="http://www.scriptics.com" target="_top">http://www.scriptics.com</a> to obtain TCL/TK and<br>
