| 摘 要： | 遥感成像中混合像元的产生是不可避免的,它的存在严重影响了遥感影像的解译精度,是传统的像元级遥感分类和面积量测精度难以达到实用要求的主要原因。介绍了混合像元存在的普遍性及对其研究的重要性,重点阐述了线性模型、概率模型、几何光学模型等几种分离方法及其它们各自的特点并对它们目前存在的不足和以后要重点研究的内容进行了讨论。最后,指出了现有研究的不足并对今后研究的重点问题给出了建议。

| Abstract: | The remotely sensed image often has many mixed-pixels,which is one of the important reasons for low interpretation accuracy.Also,it is the main reason that the normal classification based on pixel and area measure accuracy can not meet our needs.The universality of the mixed-pixel and the importance of studying on it is presented.Especially illustrates linear,probabilistic,geometric-optical model and several techniques for un-mixing the mixed-pixel.Finally,the authors think it is not enough for the recent research and give advice on the advanced study in the future. |
