Low Compexity Motion Analysis for Mobile Video Devices

This paper describes a low-complexity method for estimation of translational motion in video sequences, based on the principle that 2D image translation results in translation of image projections. The method uses a single pixel-by-pixel frame scan to extract a compact frame-descriptor. The translation between frames is determined by matching frame-descriptors using fixed-point implementation of the phase correlation method (PCM). The method gives reliable results even when video images are blurred by significant and rapid motion and in the presence of independent local motions. Real-time performance has been achieved in a low-cost DSP board.
