中值滤波技术在遥感图像处理中的应用
|
摘要
利用中值滤波技术能够很好的抑制噪声和保护边缘信息这一特性,用不同的滤波窗口对遥感图像进行处理,并做出处理后图像的归一化差值图像。通过图形分析发现差值图像上的信息比原始图像细节信息更丰富,某些地质现象更清晰。
The median filter is well known for its noise suppression and preserving edges,so we try to apply this effective method in the remote sensing image processing.We process the image by different filter-windows,and normalizational difference image for each processed image is created.We find the detailed informations from the image is richer than the oringnal image,and the geological phenomenon is easier to be identified.
