A new filtering algorithm based on image spatial clustering technique

Image filter is to remove the noise of images and try to protect the useful information as much as possible. Edge preserving & noise smoothing is to smooth the polluted image without influencing the detail spatial texture and its spatial structure much. We introduced SAS (separating the contribution of land surface and atmosphere) algorithm zhao proposed in remote sensing inversion area to image filtering area. The test result shows that the new algorithm reveals more powerful capability on protecting spatial texture protection than other algorithms.
