摘要
图像复原过程中,约束最小二乘方法一般只要求噪声方差和均值,效果较佳,应用广泛.本文在分析目前数字图像复原技术的基础上,对比研究了几种具有约束条件的最小二乘方图像复原方法,并对这些算法进行了仿真实现,对比分析了实验的结果.
In image restoration process,the constrained least squares method typically only require the noise variance and mean,is better in wide range of applications.This paper contains analysis of digital image restoration technique based on several constrained least squares image restoration methods,the simulation and also the comparative analysis of the experimental results.
