| 摘 要： | 针对遥感影像的特点，提出了一种基于多结构元素形态学的滤波算法。运用此算法和传统的中值滤波算法以及均值算法一并对遥感影像进行了处理，并且使用多种指标对处理的结果进行了比较。结果表明，该算法能够很好地滤除遥感图像中的噪声点，改进了对遥感图像的细节目标的保护。

| Abstract: | Based on the character of remote sensing image, a new mathematical morphology filtering algorithm is proposed. The algorithm, median filtering algorithm, and mean filtering algorithm are applied in remote sensing image, and their results are compared in different evaluation parameters. The conclusion proved the new filtering algorithm can well remove the noise under the condition of preserving details of the remote sensing image. |
