摘要: 本文讨论如何根据离焦模糊图象确定其退化模型参数,并同时使模糊图象复原的问题,提 出了一种基于模糊图象的梯度图象、最小二乘技术和斐波那契最优搜索法的有效方法.文中 介绍了方法的基本原理,提出了实现该方法的算法步骤,并给出了对人工模拟图象和实际拍 摄的离焦图象处理的实验结果.Abstract: In this paper, the problem of determining the model parameters of the degraded image and restoring the image from a defocused blur image is studied. An efficient method based on the gradient image of the blur image, least square restoration technique and Fibonacci optimal search method is presented. The basic principle of the method and the algorithm for the method are discussed. The experimental results are given in the paper.
