A Robust On-road Moving Platform Video Stabilization Using Derivative Curve Warping
In this paper a video stabilization technique based on derivative of integral projection curve has been proposed. The existing projection matching techniques consider only intensity values as the matching feature. Any change in pixel intensity values and their local distribution, results in shape variation of the projection curve. This shape variation affects the accuracy of curve matching and becomes a serious cause of wrong motion estimation. The proposed derivative curve technique considers the change in intensity values as the matching feature, instead of working on the intensity values itself. Inclusion of derivative provides shape information as high level feature and this results in better matching of two slightly dissimilar curves which are obvious for sequences taken from moving platform. Optimal matching of these derivative curves is achieved using Dynamic Time Warping technique.
