This paper describes an ultraTfast method ,for estimation of translational motion in video sequences. The method is based on the princkle that 2 0 image translation results in translation of imageprojections. To obtain superior robustness and accuracy we developed a multiTfranie e-xtension, which robustly integrates motion information over time. Our methodgives reliable results even when video images are blurred by significant and rapid motion and in the presence of independent local motions. The estimation process is very fast: on a standard desktop computer without using any hardwareor assembler-based optimization it works at a rate of 1400 fps (VGA frame size), exceeding real-time requirements and is typically 500 times faster than some prior-art approaches, including 2 0 phase correlation. Our method also provides a ve ry compact description of a video,frame, applicable to motion analysis and other video processing tasks in low-cost DSP systems.
