    description = ''<p>opencv_apps provides various nodes that run internally OpenCV's functionalities and publish the result as ROS topics. With opencv_apps, you can skip writing OpenCV application codes for a lot of its functionalities by simply running a launch file that corresponds to OpenCV's functionality you want.</p>
    <ul>
      <li>You can have a look at all launch files provided here (be sure to choose the correct branch. As of Sept. 2016 indigo branch is used for ROS Indigo, Jade, and Kinetic distros).</li>
      <li>Some of the features covered by opencv_apps are explained in <a href="http://wiki.ros.org/opencv_apps">the wiki</a>.</li>
