Abstract :
A methodology for optical flow analysis based on cepstral filtering is introduced. The power cepstrum is extended to multiframe analysis. A correlative cepstral technique, cepsCorr, is developed. It significantly increases the signal-to-noise ratio, reduces ambiguities, and it provides a predictive or multievidence approach to visual motion analysis
