Abstract:

In image restoration, the direction of motion blur plays an important role, which can act as an important input argument not only for image restor n but also for the length estimation of motion blur. Moreover, by knowing the direction of motion blur, we can simplify the procedure of image restoraton by converting the image into one dimensional. So the accurate estimation of motion blur direction has a great application value locally or globall In this article, as to the direction estimation of motion blur,a new and improved method based on the Radon transorm in the frequency domain is pro  d. The corresponding experiments show its accuracy and effectiveness.

Key words: image degradation, image restoration, point spread function（PSF） ;direction of motion blur
