Do you know any sources with background subtraction from moving camera? I want to write something similar to this: http://vimeo.com/72577177

There is a lot of materials about movement detection with still background, but I can't find any code sample with moving background.

edit: I thought about optical flow and removing background by detecting the biggest number of similar vectors. Could it be that simple?

Here are two research articles on this topic:

  • Mittal, A. et D. Huttenlocher. 2000, «Scene modeling for wide area surveillance and image synthesis» in Proceedings of the IEEE Conference on Computer Vision and Pattern Recognition (PDF)

  • Hayman, E. et J. Eklundh. 2003, «Statistical background subtraction for a mobile obser- ver», in Proceedings of the IEEE International Conference on Computer Vision. (PDF)
