MATLAB Code Implementation for Image Registration

This MATLAB-implemented image registration code provides a user-friendly graphical interface (GUI) supporting pixel-level precision operations. The codebase incorporates core functionality for performing basic geometric transformations including translation, rotation, and scaling through matrix manipulation and interpolation techniques. Users can select from multiple registration algorithms such as intensity-based correlation methods or feature-based approaches using SURF/SIFT detectors, with parameters configurable via GUI controls. The implementation handles image preprocessing, transformation matrix computation, and spatial interpolation using bilinear or bicubic methods. Suitable for scientific research, engineering applications, and image processing workflows, this solution enhances processing accuracy through automated landmark detection and optimized similarity metrics (e.g., MSE or mutual information). The object-oriented architecture ensures modular algorithm integration and real-time preview capabilities for transformation results.
