| 摘 要： | 如何通过充分考虑地物复杂性和地域时间限制,提高混合像元分解算法的精度和普适性,是目前基于中低分辨率遥感数据进行湖泊面积监测所面临的主要问题。针对问题,提出了一种结合双边界提取和混合象元分解的高效算法,最后基于AVHRR数据对中国东北,内蒙古地区的湖泊面积变化进行遥感监测,验证了算法的高精度和可行性。

| Abstract: | The major difficulty in monitoring lake areas based on moderate or low resolution RS data is how to improve the accuracy and applicability of decomposition of mixed pixels,considering both the complexity of objects and limitations of time and space.To solve the problem,this paper proposes an efficient model combing double-edge extraction with decomposition of mixed pixels,the accuracy and applicability of which is attested by computing lake areas of northwestern China using AVHRR images. |
