Conventional hyperspectral unmixing generally includes two steps:endmember selection and mixed pixel decomposition. Nevertheless,the non-completeness of ground object spectral library and the existence assumption of pure pixel of each endmember lead to the unsatisfactory unmixing results.
传统的光谱解混一般包含端元选择和混合像元分解两个步骤,不过,地物光谱数据库的非完备性以及每种地物类别对于纯像元的存在性假设导致该方法的解混效果并不理想。
