和魏纳滤波,约束最小二乘滤波器等复原方法相比,Lucy-Richardson算法不需要事先预知噪声信息,有更广泛的适用性,但Lucy-Richardson算法极易引起噪声放大的缺点。提出改进的Lucy-Richardson图像盲复原新算法,仿真结果表明,该算法在噪声抑制、稳定性、细节保存以及视觉效果方面都优于原有Lucy-Richardson算法。
Compared with Wiener Filter and Constrained Least Square Filter,Lucy-Richardson algorithm has wider applicability because c no need to know the noise information beforehand.But it also brings disadvantage of magnifying the noise.The paper puts forward a new im proved method of blind image restoration.According to the simulative experiment,the results show that the new algorithm outperforms the ol Lucy-Richardson algorithm in noise restraint,stability,details preservation and visual effect.
