| 摘 要： | 利用一组标准正交化的参考向量得到一个可能匹配区域,排除了绝大部分不可能匹配的样本,从而大大提高光谱预选筛分的速度;同时介绍了一种平衡速度与精度的编码替代算法。实验证明:压缩影像的目视效果较好,未产生边缘模糊及条带现象;采用自动目标生成方法(ATGP)从样本集中提取端元并进行光谱角度制图,其效果令人满意。

| Abstract: | Using an norm orthonormal set of vectors,on defining a possibility match zone outside most of the exemplars which can not be matched,the prescreening method was accelerated,and a replacement algorithm which balanced the quality with speed was introduced.Our experimentation proveed that: the compress image had a good effect by view,with no fuzz and strip phenomenon: The result was more satisfactory by extracting endmembers from exemplar using the algorithm namely automatic target generation process than using SAM to classify the compress data set. |
