文摘

Tilt estimation using correlation of multiple differential-Radon angular slices. Novel multi-constraint warping is proposed for error prone boundary-vector removal. Warping singularities are removed using interest vectors based on optima matching. Slope of extracted interest vector is utilized for inter-frame zoom estimation. A new affine video stabilizer framework based on derivative-projection is proposed.
