ecto_ros: ROS Integration & Bagfile Support

ecto_ros contains publishers, subscribers, bag readers and bag writers for many common ROS message types. You can place subscribers as the inputs to your graph and publishers at the outputs, using converter cells as necessary (for instance, to get from Image messages to cv::Mat objects).

./ /input:=/camera/rgb/image
