Convert back depth_registered/image_raw to depth/image_rect

edit

Hi, I have recorded 4 topics in a rosbag: camera/depth_registered/camera_info, camera/depth_registered/image_raw , camera/rgb/camera_info, camera/rgb/image_raw .

I am running an upper body detector that uses the unregistered depth image /camera/depth/image_rect and does not work with any depth registered versions.

Is it possible to generate the unregistered depth images from the above recorded topics in the rosbag?

Any help is appreciated!! Thanks
