Fourier-Mellin Transform-Based Registration System Implemented in MATLAB

A MATLAB-based image registration system utilizing Fourier-Mellin transform algorithm, where executing fm_gui.m launches the demonstration interface. The left-side image panels allow selection of two input images for registration with support for zoom and rotation transformations. The right-side control panel includes "Window" dropdown for filter selection, "Rotation"/"Scale"/"Log-polar" options for interpolation methods, and "REGISTER" button with slider for peak point selection. Registration results display in bottom panels with transformation parameters shown in "Translation"/"Rotation"/"Scale" fields.
