Rapid Manipulation Method for Massive Remote Sensing Images Based on LRU Algorithm

摘要

With the rapid development of remote sensing (RS) technology, RS image data is growing larger and larger, which makes general image manipulation method limited in feasibility, speed and efficiency. In this paper, a rapid manipulation method of massive RS data based on Least Recently Used (LRU) algorithm in operating system page scheduling is proposed. Its core content includes data read-write based on memory mapping, data organization based on image pyramid with layers and blocks and caching based on LRU algorithm. The experiment shows that this method can greatly increase the speed and efficiency of massive RS images processing.
