Modify images in an existing rosbag

I currently have a rosbag with existing camera, lidar, radar and other information. I only want to modify the content of several images in one of the camera topics. Is there a way I can do that? Thanks!

Yes, there are a few examples how to do something similar (like: adjusting timestamps, adding metadata, ...) on the rosbag Cookbook wiki page.

Depending on how you plan to modify the images, the C++ example at the end might be a good start and then you can go crazy with whatever OpenCV provides :-)

Does that help?
