A new phase-based motion algorithm is introduced. The estimation is performed such that only non-aliased temporal frequencies are included in the calculation of the translation vector describing the displacement of an object in a digital video sequence. A full description of the algorithm is presented. It is based on using a two-dimensional fast Fourier transform in two consecutive video fields or frames. Simulation results are included to illustrate the capabilities of the algorithm in an object-tracking application featuring fast frame-to-frame motion. It is shown that the proposed algorithm out-performs a conventional phase-based motion estimation algorithm.
