| Abstract: | Through analyzing the degraded image model and related point-spread functions, they show that Parzen-window function has some characteristics which are similar to point-spread function. A method to estimate the point-spread function based on Parzen-window function is proposed. The technique for blind recovering image with probability and estimation theory is explored. The work described is of both theoretical and practical meanings for the applications of digital image processing. |
