A group of high pass digital filters were constructed by several finite difference operators with different orders,and the image was processed with these operators and the variance was estimated separately from the filtered data with Inter-Quartile Range(IQR) method.
采用不同阶次有限差分算子构成一组高通滤波器,分别对图像滤波处理,并将四分位间距(IQR)方法与中值滤波原理结合,估计CRB分析中的噪声方差,避免了残留轮廓信息的复杂处理,实验表明算法简单有效。

考虑到震前电离层TEC异常扰动探测方法(主要包括平均数法、中位数法、四分位距法等)的局限性,提出采用电离层TEC拟合后的剩余残差来识别TEC异常,即先对电离层TEC时间序列进行拟合,然后利用滑动时窗法进行异常识别。
