Image sequence stabilisation based on DFT filtering
S. Ertürk, Tim J. Dennis · IEE Proceedings - Vision Image and Signal Processing · 2000
An image sequence stabilisation system based on DFT filtering of absolute frame displacements to compensate for undesired fluctuations in the sequence by shifting image frames into correct positions is reported. The system compensates for undesired jitter, while preserving desired global camera motions. Robustness is introduced to interframe motion estimation by averaging motion vectors detected in the phase correlation surface.
