| 摘 要： | 通过对"背景"、"干扰"与"异常"在二维散点图的空间结构分析,选取最优提取蚀变信息的波段组合。结合"遥感蚀变信息多层次分离提取"模型,主要采用二维相关彩色编码技术与Mask技术逐步去除干扰信息,实现蚀变异常二次提取,使得矿化蚀变信息一步步分离提取出来。实践证明此方法在解决地物混合复杂的地区的遥感蚀变信息提取中具有良好的效果。 |

| Abstract: | Through analyzing the background,interference and alteration anomaly in two-dimensional scatter chart of spatial structure,this article combines with multi-layer extracting alteration information of remote sensing model,and uses two-dimensional color encoding method and mask technology to extract the alternation information twice.It’s demonstrated that this method has gained a good effect in complex mixing land cover area. |
| Keywords: | alteration index two-dimensional color encoding method two-dimensional scatter chart spatial structure analysis alteration information extraction |
