Abstract :
Translation, rotation and scale stabilisation of image sequences is presented with phase correlation based estimation of motion parameters. Phase correlation and log-polar magnitude spectra representation is utilised to obtain translation, rotation and scale parameters. Stabilised frame positions are obtained through Kalman filtering of absolute parameters, and image frames are processed accordingly so as to result in a sequence that displays smooth global movements only.
