Switching Median Filter, Extremum Median Filter, Adaptive Median Filter - MATLAB Implementation

This repository contains M-file source code implementations of switching median filter, extremum median filter, and adaptive median filter algorithms. The program achieves results comparable to those presented in academic papers, providing practical MATLAB implementations for image denoising applications.

Median Filtering with Noise Detection

This noise-detection-based median filtering approach first identifies noisy pixels through neighborhood analysis, then applies switching median filtering. Unlike traditional methods, pixels classified as noise are excluded from median filtering calculations for other pixels, effectively removing noise while better preserving image details. Key implementation involves threshold-based noise detection algorithms and conditional filtering logic.
