The Frequency Domain Noise Filter is an Image Processing project that combines Wavelet decomposition and Magnitude spectrum view, built with Matplotlib. The project follows a clean, modular pipeline where image input, processing, and presentation stay separated, making it easy to test, extend, and present. It showcases practical Image Processing techniques while producing a working, demo-ready application.
Manual processing and analysis of images for this task is slow, inconsistent, and cannot handle large volumes of data. Without an Image Processing approach built on Magnitude spectrum view and Matplotlib, users cannot automatically enhance, restore, or analyze visual content, and there is no reliable way to measure the quality of the results.
This project applies Image Processing techniques through Wavelet decomposition, orchestrated with Matplotlib and Magnitude spectrum view. The pipeline is designed for quality and control, with preprocessing, algorithm selection, and clear evaluation. It produces consistent, reusable results and can be adapted to related image tasks with minimal changes.

The project is layered: the input layer loads and preprocesses images through Wavelet decomposition; the processing layer applies image algorithms with Matplotlib and Magnitude spectrum view; and the output layer formats and presents results via High-pass filtering. Shared configuration, logging, and evaluation modules support all layers, keeping the system robust and easy to extend.
