Abstract
In this paper, we present an algorithm to deblur the images degraded by the circular motion. We consider that the motion is driven by a constant acceleration and the point spread function is assumed to be unknown. Therefore, we perform motion estimation algorithms before deblurring the images. To deblur the images, we use a bidiagonalization algorithm employed together with Tikhonov regularization. Motion deblurring is perfomed at each circular motion path. The circular motion paths are obtained by using a digital circle generating algorithm. To obtain the complete deblurred images, deblurring results are combined. As the deblurred images are distorted by the empty pixels, the median filter is used to keep the images intact. Experimental results show the feasibility of the presented motion deblurring algorithm.
