Abstract

Image restoration requires correct estimation of point spread function from the degraded observation. When one point spread function acts on the whole image, estimation of the true image is easier. However, for spatial variant degradations, i.e., when number of point spread functions act on the image, it is very difficult to estimate the true image from the degraded observation. In this paper, we have addressed rotational motion blur problem which may be either circular or elliptical. Spatial variant degradation is converted to number of spatial invariant degradations and the principle of spatial variant restoration is applied. The restoration results indicate the efficiency of the proposed method.
