In the imaging process of the space remote sensing camera
there was degradation phenomenon in the acquired images. In order to reduce the image blur caused by the degradation
the remote sensing images were restored to give prominence to the characteristic objects in the images. First
the frequency-domain notch filter was adopted to remove strip noises in the images. Then using the ground characters with the knife-edge shape in the images
the point spread function of the imaging system was estimated. In order to improve the accuracy
the estimated point spread function was corrected with Gaussian fitting method. Finally
the images were restored using the adaptive Wiener filtering with the fitted point spread function. Experimental results of the real remote sensing images showed that almost all strip noises in the images were eliminated. After the denoised images were restored
its variance and its gray mean gradient increased
also its laplacian gradient increased. Restoration with Gaussian fitted point spread function is beneficial to interpreting and analyzing the remote sensing images. After restoration
the blur phenomenon of the images is reduced. The characters are highlighted
and the visual effect of the images is clearer. 2011 IEEE.
