Abstract
An image sequence stabilisation system based on DFT filtering of absolute f rame displacements to compensate for undesired fluctuations in the sequence by shifting image frames into correct positions is reported. The system co mpensates fur undesired jitter, while preserving desired global camera moti ons. Robustness is introduced to interframe motion estimation by averaging motion vectors detected in the phase correlation surface.
