From Noise to Clarity: Filtering Techniques in Biomedical Imaging

📋 Overview

This project explores filtering techniques in biomedical image processing, focusing on noise reduction and feature preservation in MRI images.

🎯 Objectives

  • Implement filters: Mean, Gaussian, Bilateral, and Adaptive.
  • Evaluate performance using SNR and PSNR.
  • Analyze filter effectiveness on noisy MRI images.

🧪 Structure

  1. Image Aspects: Frequency domain analysis, low/high-pass filters.
  2. Noise Modeling: Statistical analysis, noise addition, SNR.
  3. MRI: Noise sources and reduction techniques.
  4. Filtering: Implement filters without built-in functions, evaluate results.
  5. Adaptive Filtering: LMS algorithm, parameter tuning.
