空间域图像去噪方法

A Study on the Method of Image Noise Removal in the Spatial Domain

在图像的采集、获取、编码和传输过程中,所有的图像均不同程度地被可见或不可见的噪声"污染"。文中就空间域图像两种不同去噪方法线性滤波和中值滤波进行了比较研究,将线性滤波与非线性滤波有机地结合。通过大量实验,得出应用混合滤波器的图像去噪方法。

During the collection, acquisition, coding and transmission of the images, they are all (inclusively) polluted by the noise that can or can not be seen on different degrees. There exist two (different) methods that can remove noiselinear filtering and medium filtering. In this article, these two methods are compared and combined organically. By trials, the mixed method for image noise removal is obtained.
