#### Software Architecture
Software architecture description

The vision_opencv stack provides packaging of the popular OpenCV library for ROS. For information about the OpenCV library, please see the OpenCV main page at http://opencv.org/ links to complete documentation for OpenCV, as well as other OpenCV resources (like the bug tracker on http://code.opencv.org/)
