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.

In terms of large field view and multi-channel TDICCD remote sensing images
previous interpolation methods and curve fitting methods are not able to achieve the high accuracy and fast registration
and their noise immunity and robustness is not high. For that
this paper presents a more accurate and faster method
iterative pixel interpolation and surface fitting method. Firstly
the method uses the some overlapping pixels between multi-channel images. Secondly
the proposed technique
which is based on the maximization of the correlation coefficient function
combines an efficient pixel-moving interpolation scheme with surface fitting
which makes use of accurate interpolation calculation and fast surface fitting in the iterative process. Finally
the accuracy and speed of the algorithm is evaluated by sub-pixel registration of multi-channel images and comparison with other sorts of efficient methods. The experiment results show that the accuracy of the method reaches 0.01 pixels and it is 3 times faster than the interpolation method. In the registration of large field view and multi-channel TDICCD images
the method is accurate and fast
with greatly high stability
noise immunity and robustness. 2010 IEEE.
