This paper presents a method to adopt phase correlation for blurred frames. Phase correlation is a strong motion estimation tool which is highly robust against noise, However, phase correlation is not robust against blur degradation in frames. In scenarios where only one of the frames is blurred or when the two frames have different blur extents, phase correlation does not achieve an accurate estimation of the motion vector. We also show that the number of motion vectors estimated by the block-matching technique is reduced in such scenarios, therefore, a technique to estimate the motion in such scenarios is strongly needed. We investigate the effects of blurring on motion estimation and show the effectiveness of our algorithm for motion estimation in blurred frames and compare it against existing methods.
