| Abstract: | In this paper,the change detection methode of utilizing aviation images' grey level difference and ratio was mainly studied.In order to analyse this two kinds of methods,a group of aviation images taking farmland as main landscape of the whole view was measured.According to the result of experiments presented by the form of black-and-white pictures,while relatively choosing different threshold value,these two kinds of methods were compared,especially in the use of detecting the result through the change of ... |
