摘要：

In this paper, we use adaptive rank-order filters for localization and extraction of desirable details from images. To improve the performance of linear correlations, we use novel local adaptive correlations based on nonparametric Spearman's correlation. These filters are based on correlation between the ranks of the input scene computed in a moving window and those of the target. Their performance and noise robustness are compared with those of the conventional linear correlation. Computer simulation results are provided and discussed.
