【摘要】 利用Doris软件对伊朗Bam地震ENVISAT图像进行处理,得到InSAR差分干涉图并对InSAR差分干涉图进行了相位解缠;然后用几种边缘检测算法对解缠后的差分图进行边缘检测以提取地面断裂带的位置,最后对这几种边缘检测算法的检测结果进行了评价。更多还原

【Abstract】 This paper describes the application of edge detection to identify the ruptured fault segment in phase-unwrapped interferogram.It first uses the Doris soft and Envisat SAR images to generate the differential SAR interferogram over Bam city of Iran,followed by the phase unwrapping of the differential interferogram.Then,this paper applied several edge detection techniques to examine the ruptured fault segment in the phase-unwrapped interferogram.Finally,the results are compared and evaluated.更多还原
