speckle noise

基本解释

Speckle noise suppression gets stronger in homogeneous regions as the window size increases succeedingly.
在均匀区域，随着窗口大小的增大，斑点噪声抑制变得更强；
Due to the complicated background of objectives and the speckle noise in the high-resolution SAR images, it is almost impossible to extract roads directly from original remote sensing images.
由于高分辨率SAR图像中，目标背景复杂，同时由于受相干斑噪声的影响，因此很难直接从原始图像数据中提取道路特征。
