I don’t know how to run the file contour_moments.cpp that’s able in this github link: https://github.com/ros-perception/vis...

I’m working with Indigo and I have installed OpenCV3 following this ROS.org link: http://wiki.ros.org/vision_opencv

when i run the command rosrun opencv_apps contour_moments it only appear a warning and nothing else:

[ WARN] [1450293289.992148166]: Topic 'image' has not been remapped! Typical command-line usage:
    $ rosrun image_rotate image_rotate image:=<image topic> [transport]

which topic should I use?? (I'm using a kinect, and it is working fine)
