ROS packages useful for Computer Vision tasks

The great advantage of doing Computer Vision in ROS is the fact that we do not have to re-invent the wheel. A lot of third-party software is available, and we can also connect our vision stuff to the real robots or do some simulations. Here, we are going to enumerate interesting Computer Vision tools for the most common visual tasks, but we will only explain in detail one of them later, including all the steps to set it up. We will do it for visual odometry, but other packages are also easy to install and it is also easy to start playing with them; simply follow the tutorials or manuals in the links provided here:

• Visual Servoing: Also known as Vision-based Robot Control, this is a technique that uses feedback information obtained from a vision sensor to control the motion of a robot, typically an arm used for grasping. In ROS, we have a wrapper of the Visual Servoing Platform (ViSP) software (http://www.irisa.fr/lagadic/visp/visp.html, http...
