Combining two complementary iterative versions of median filter extended to an even (2 × 2) pixel set, results in efficient edge-preserving removal of impulsive image noise. Enhance spike suppression capability for heavy noise, MAE and visual comparisons show improvements over median filter.

Abstract
Combining two complementary iterative versions of median filter extended to an even (2 × 2) pixel set, results in efficient edge-preserving removal of impulsive image noise. Enhance spike suppression capability for heavy noise, MAE and visual comparisons show improvements over median filter.
