Viewing image data: usb_cam

edit

HI, I'm trying to publish my image data from usb_cam to the following topics.

I'm not sure on how do i create a node that would communicate with these topics

/base_waypoints
/camera_info
/current_pose
/current_velocity
/final_waypoints
/image_color
/image_color/compressed
/image_color/compressed/parameter_descriptions
/image_color/compressed/parameter_updates
