摘要
根据地物的自然连续性，认为混合象元中最终光谱单元的组成与其邻域相关，据此提出了一种十分简单的混合象元解译方法———基于邻域的混合象元解译．给出了解译的基本步骤与线性算法，讨论了最终光谱单元的标准及其搜集方法，并探讨了混合象元中与邻域无关的孤立最终光谱单元的探测问题．
According to the successive property of the ground objects, composition of the spectral endmembers in mixed pixel is considered to be relative with its neighbor fields. Based on this hypothesis, a very simple method for interpretation of a mixed pixel is proposed:neighbor field based mixed pixel interpretation. the primary interpretation steps and its linear arithmetic are also offered. The difinition and collecting method of spectral endmember are discussed and the detection of isolate spectral endmember which has nothing to do with its neighbor fields is discussed, too.
