Image deblurring by using the estimation of PSF parameters for image devices

The parameters of a point spread function consists of the length and angle of the blur kernel. The deblurring performance is affected by the estimation accuracy of two PSF parameters. In this paper, we propose the method of the PSF parameters estimation and the image reconstruction by using the periodicity of motion blurred images in the frequency domain. Experimental results show that the proposed method estimates the PSF parameters more accurately than the existing ones.
