SAR speckle suppression by method of heterogeneity measurement
SAR图像异质性测量在相干斑抑制中的应用*

The filter algorithm for speckle based on the ratio of arithmetic to geometric mean is immature.This paper used the ratio of arithmetic to geometric mean to replace the coefficient of variation and applied into the enhanced adaptive filters. It proposed the novel class of adaptive filters, which were based on the ratio of arithmetic to geometric mean and were designed for speckle. Through simulation, verified the effectiveness and superiority of the novel class filters.
