摘要 经典的基于比算子的差异图构造方法,主要是针对单一像素进行运算,因此影像噪声对差异图有一定程度的影响。将模糊贴近度应用于差异图的构造过程中,利用经典算子和模糊贴近度分别构造差异图;然后对差异图进行双边滤波和灰度过渡区域提取,从而确定影像分割阈值,得到两期影像变化结果;最后采用相关的参数指标对结果进行分析评价。结果表明,模糊贴近度差异图在SAR影像变化检测中的效果更好。 The classic ratio operator-based difference map construction method mainly operates on a single pixel,so image noises influence the difference map to a certain extent.Firstly,we used the classic operator and the fuzzy closeness to construct difference maps respectively.Then,we performed bilateral filtering and gray transition region extraction on the difference maps and determined the image segmentation threshold to obtain two-period image change results.Finally,we used relevant parameter indicators to analyze and evaluate the results.The results show that the fuzzy closeness difference map is better in SAR image change detection.
