Adaptive L-Filters Based On Local Statistics
Tong Sun, Moncef Gabbouj, Yrjo A. Neuvo · 2005
An adaptive order statistic filter (L-Elter) based on local statistics is introduced. Such an estimator is particularly effective in Eltering signals which are corrupted by more than one type of noise, e.g additive Gaussian noise plus impulses. In order to further improve the filtering performance (detail preserving ability), the adaptive structure has been combined with weighted median operations which use temporal irrormation. Simulation results are included to assess the performance of the proposed adaptive structure.
