Data Fusion Based Technology for Remote Sensing Image Processing
基于数据融合的遥感图象处理技术

Data fusion is a powerful tool to process tremendous remote sensing data for its capability to combine useful information of multisource or multitemporal data, and eliminate their redundancy, so it has been applied on many areas extensively, especially, on remote sensing image processing. At first, this paper simply reviews the necessity of data fusion's appearance and development, together with several definitions brought forward by several investigators. Afterwards, this paper not only attempts to analyze the Data Fusion Engine framework and configuration comprising of pixels-level?feature-level and decision-level fusions detailedly, but also principally analyze the fusion methods and their applications of each data fusion level. In addition, because of close relation between data fusion and image classification, object detection, change detection, and target recognition, these data fusion based applications are also analyzed briefly. Finally, summary and prospect are described.
