中文摘要	传统的图像滤波器在抑制噪声的同时会丢失图像中的边缘和细节。借鉴遥感图像聚类方法,并对其加以改进,提出空间聚类方法。空间聚类方法重视图像空间分布模式的判别与保护,可有效分离出有噪图像中对视觉效果影响较大的噪声。在信噪分离的基础上,对噪声点加以滤波操作,对相对无噪声像元点则采用加权均值融合处理。实验证明,此方法一方面保证了图像的去噪效果,另一方面最大可能地保存了图像中没有被噪声污染的边缘和细节信息,并且对多类噪声甚至混合噪声均有较好的效果。; Some traditional image filters may lose detailed spatial information while controlling noise. The remote sensing image cluster algorithm was introduced and improved, and then a spatial clustering method was presented. Spatial clustering method was helpful to distinguish and protect the image spatial patterns, and was used to separate louder noise that affected the image visual effect. Based on the separation of noise points set (NPS) and signal points set (SPS), NPS was filtered and SPS was fused with weighted averaging method. The result shows that new filter based on spatial clustering technique can remove the image noise. Furthermore, it can protect unpolluted detailed spatial information as much as possible. Better filtering result is got on the case of multi-noise.
