【讲座摘要】

       对地观测卫星提供遥感数据具有丰富的空间，光谱和时序特征。为了更加充分利用这些信息，很多图像融合 的方法已经被提出。图像融合主要指同时利用两个甚至更多的图像去改进图像质量。融合之后的图像具有更 为丰富的信息且为改善图像分析提供帮助。比如，图像融合在分类、分割等方面可以带来比单个图像更好的 效果。本次报告主要回顾目前经典的在遥感应用中的图像融合方法。

   Earth observation satellites provide data covering different parts of the electromagnetic spectrum at different spatial, spectral, and temporal resolutions. To utilize these different types of image data effectively, a number of image fusion techniques have been developed. Image fusion is the set of methods, tools, and means of using data from two or more different images to improve the quality of the information. The fused image has rich information that will improve the performance of image analysis algorithms. This increase in quality of the information leads to better processing (ex: classification, segmentation) accuracies compared to using the information from one type of data alone. An investigation into the use of various concepts of image fusion in remote sensing applications will be presented.
