This video describes our research on video stabilization to be presented at SIGGRAPH 2009.
We describe a technique that transforms a video from a hand-held video camera so that it appears as if it were taken with a directed camera motion. Our method can adjust the video to appear as if it were taken from nearby viewpoints, allowing for 3D camera movements to be simulated. By aiming only for perceptual plausibility, rather than accurate reconstruction, we are able to develop algorithms that can effectively recreate dynamic scenes from a single source video. Our technique first recovers the original 3D camera motion and a sparse set of 3D, static scene points using an off-the-shelf structure-from-motion system. Then, a desired camera path is computed either automatically (e.g., by fitting a linear or quadratic path) or interactively. Finally, our technique performs a least-squares optimization that computes a spatially-varying warp from each input video frame into an output frame. The warp is computed to both follow the sparse displacements suggested by the recovered 3D structure, and avoid deforming the content in the video frame. Our experiments on stabilizing challenging videos of dynamic scenes demonstrate the effectiveness of our technique.

You can try Syntheyes to make simular 3D stabilized video. Autors of this and like you, you are suxx, becouse you do not distribute all of you "cool research" programms to public in any form. It is not so good.
Make a research paper ? Make available software you are use to public.
i agree with you tr1tan, but i think you are going to lose some of the video resolution anyway. When software programmers will find a way to don't have to zoom into a frame by keeping a sort of "virtual pixels" at the edges of the frame...there you go!
the only way that could be done is if the program was complex enough to "create" the edges of the frame that are no longer in the frame when the camera shakes off center. The program would have to be able to "think" and be able to determine what is there based in the 3d motion of the objects calculated from frames in the video where they are visible.
Also if a new entity were to emerge or an object was to move off frame, the program would have to be able to determine how it moved based of info that is not available which is impossible within the constraints of a traditional camera. if a camera was made with a 3d laser scanner that had a range larger than that of the cameras frame then it could be possible.
Much better than other methods, but its not gonna replace a Steadicam. Like all stabilizing software, it crops the image. This both reduces resolution and makes framing the shot difficult. By the way guys, this isn't gonna be freeware or anything. I'm sure Adobe will add this to After Effects eventually(note that the credits include Adobe Systems and Univ of Wisconsin-Madison)
