摘要
通过对降质图像离散退化模型与Parzen窗估计法基本公式的对比和对几种退化模型的点扩展函数特点的分析 ,揭示了点扩展函数与Parzen窗函数之间的对应关系 .提出用Parzen窗函数对点扩展函数进行估计的思路和方法 。
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.
