摘要
通过对复原处理大噪声高斯型模糊图像过程中存在的问题进行分析,针对图像复原处理中最常见的维纳滤波器,设计了可对大噪声进行有效预处理的前置滤波器,并采用计算机模拟滤波对前置滤波器的效果进行验证.结果表明:当噪声较大时,前置滤波器具有良好效果,是一种行之有效的图像复原方式.
By analyzing the problems in the process of restoration of Gaussian blurred images in strong noise,a pre-filter that could pretreat strong noise effectively is designed based on the Wiener filter,and the effects of the pre-filter are verified by computer simulation.The results show that the pre-filter performs very well and is an effective method for restoration of image
