MATLAB Implementation of Image Frequency Domain Filtering

This is an image frequency domain filtering program developed as a course design project through complete independent development. The program implements high-pass filtering, low-pass filtering, band-pass filtering, and directional filtering functionalities using frequency domain transformation techniques. The implementation likely involves Fast Fourier Transform (FFT) for converting images to frequency domain, followed by application of various filter masks (such as Butterworth or Gaussian filters) in the frequency domain. Additionally, the program features a Graphical User Interface (GUI) built using MATLAB's App Designer or GUIDE, which provides an intuitive and user-friendly interface for parameter adjustment and real-time filtering visualization. The GUI components probably include sliders for cutoff frequency adjustment, dropdown menus for filter type selection, and interactive panels for displaying original and filtered images side by side.
