       Most of existing techniques to estimate camera motion are based
       on analysis of the optical flow. However, the estimation of the
       optical flow  supports only a  limited amount of  scene motion.
       In this report, we present  a novel approach to estimate camera
       motion  based on  analysis  of local  invariant features.  Such
       features  are  robust  across  a substantial  range  of  affine
       distortion.   Experiments  on synthesized  video  clips with  a
       fully controlled  environment show  that our technique  is more
       effective than the optical flow-based approaches for estimating
       camera motion with a large amount of scene motion.
