Is there a way to extract a person from a video without having a blue- (or green-)screen?
Any software which can do this?

If you have a frame where the person does not exist, you can use a tool called a difference matte. (You'll need to scroll down to the section titled "Difference Matte Effect" for a description.) It will find a difference between the frame without the person, and the frames with a person and remove areas that are the same, leaving only the difference (in this case the person). As linked, After Effects has such a tool. Many other video editors have it as well.

Thanks, let me just link the following thread, which also mentiones other software for achieving this: video.stackexchange.com/questions/4306/…– StefanHMay 21, 2017 at 20:57
Final Cut Pro X has a plugin called Pro Removal that can remove moving things from the scene on fixed camera shots.
Also there is a tutorial for After Effects that shows how remove objects from scene using the tracker.
Also you can clean frame by frame using Photoshop or similar if you have a good amount of time to spend or a crew to help you in the task.

Thanks for the answer! Unfornutaley I do not have both programs, so may I ask is there any freeware or open-source program out there that can accomplish this task... would be glad if you can add them to the list!– StefanHMay 16, 2017 at 21:55

You could use the compositing tools in Blender to do this. Blender is free.– stibMay 18, 2017 at 12:43
