this is the link : http://wiki.ros.org/cv_bridge/Tutorials/ConvertingBetweenROSImagesAndOpenCVImagesPython in the step 4 : i am not sure if we have to add : sensor_msgs,opencv2,cv_bridge,rospy,std_msgs in package.xml file which locate in /opt/ros/indigo/ardrone_autonomy or in another file

then in the example code : line 3 : roslib.load_manifest('my_package') my_package it means the same package which we have to add : ensor_msgs,opencv2,cv_bridge,rospy,std_msgs ?
