Fast View of Mass Remote Sensing Images based on Image Pyramid

摘要：

In this paper,a fast view scheme of mass remote sensing images based on image pyramid is described and implemented.The key techniques in this scheme are tiling,image pyramid,and cache scheduling management.This scheme employs tiling to break the limit of the Windows process memory and improve the I/O speed of hard disk.A wavelet based image pyramid is built for multi-resolution displaying.Cache scheduling management is used for reducing the time latency of image loading.In the case of dragging an image,the viewer uses the existing tile in cache to quickly update the view and replaces the tiles in cache corresponding to the updated view.The experiment results show that this scheme is effective in fast view of mass images.
