Estimation of motion blurring direction by rotated accumulation method

Liu Y., Gao C., Kuruoglu E. E.

Motion blur  frequency domain  Rotated Accumulation method  motion direction 

Motion blur is usually caused by the motion between the camera and the scene during integration time of image. And the estimation of motion blurring direction is vital to restoration. There are existing methods such as Radon and cepstrum based approach. In this paper, a Rotated Accumulation Method by selecting the minimum value of rows in frequency domain is introduced to find the motion direction. Also, it is shown that this method is more advisable than spatial based method when the motion length is relatively small or the image is blurred by noise, and more accurate comparing to Radon method.
