+  @defgroup 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 @cite OF06 and @cite G11 . However, there are some extensions and deviations from the original
+paper methods.

+         @defgroup videostab_motion Global Motion Estimation
+
+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.
+
+         @defgroup videostab_marching Fast Marching Method
+
+The Fast Marching Method @cite 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.
