Module opencv::videostab

Video Stabilization

The video stabilization module contains a set of functions and classes that can be used to solve the problem of video stabilization. There are a few methods implemented, most of them are described in the papers OF06 and G11 . However, there are some extensions and deviations from the original paper methods.

The video stabilization module contains a set of functions and classes for global motion estimation between point clouds or between images. In the last case features are extracted and matched internally. For the sake of convenience the motion estimation functions are wrapped into classes. Both the functions and the classes are available.

The Fast Marching Method Telea04 is used in of the video stabilization routines to do motion and color inpainting. The method is implemented is a flexible way and it’s made public for other users.
