From PatchMaking: PatchMaker is a 2D motion tracking program designed for intraframe video editing and compositing. It can determine the motion of a selected object in the scene to a subpixel precision under a specified parametric motion model. The computed motion can be used to solve the following tasks: 1) Placing a patch on a moving object. 2) Background stabilizing (eliminating unwanted motion in the scene caused, for example, by camera jerks).
