%X In order to restore the degraded image, the first step is to give the estimation of the blur scale. Blur scale identification based on the autocorrelation of projection was proposed aiming at the motion blurring. The movement direction was transformed into horizontal direction, firstly computing the horizontal derivative of blurred image, and secondly computing the vertical derivative of the horizontal derivative of blurred image. Then, the autocorrelation curve of the projection for the vertical derivative was drawn, and the degradation scales were equal to the distance of maximum and minimum values of the autocorrelation function.
