| Abstract: | Computing load of preprocessing of remote-sensing image is so large that completing calculation in real time becomes very difficult.For completing fast and effective preprocessing,by analyzing key parts of processing progresses,topological structure of parallel process is designed based on 2D-Mesh structure,and processing performance is discussed.The design can improve the performance of preprocessing system to a large extent and improve the system sture ture of parallel of remote-sensing image. |
