在使用地球资源卫星进行农、林、矿等各种资源调查中,需要处理极其大量的数据。对数据分类是各种处理中最费机时的操作。提高分类器的速度将可缩短处理周期,降低处理费用。因此寻找快速算法一直是人们努力解决的课题之一。 利用微型机处理数据时,运行时间长的问题尤其严重,这大大限制了遥感技术的推广和普及。作者在遥感应用软件的研究中,利用MSS数据是整型,且动态范围较窄的特点, The use of Earth resources satellites for farming, forestry, mining and other resource surveys need to deal with extremely large amounts of data. Data classification is the most expensive operation in various processes. Increasing the speed of the classifier will shorten the processing cycle and reduce the processing cost. Therefore, finding fast algorithms has always been one of the topics that people are trying to solve. The problem of long running time is particularly serious when using the microcomputer to process data, which greatly limits the popularization and popularization of remote sensing technology. In the research of remote sensing application software, the author makes use of the characteristic that MSS data is integer and its dynamic range is narrow.
