GUI-based Image Registration Program Using Maximum Mutual Information

The maximum mutual information-based image registration program is an algorithm designed to align two images with high precision. This implementation computes the statistical dependency between two images using mutual information metrics, then automatically optimizes spatial transformations (including translation and rotation parameters) to achieve optimal alignment. The core algorithm typically involves gradient-based optimization methods like gradient descent or more advanced techniques such as stochastic optimization to maximize the mutual information measure between image intensity distributions. The application features a comprehensive GUI interface that enables users to intuitively load source and target images, configure registration parameters, visualize real-time transformation progress, and export results. Key functions include histogram calculation for joint probability distribution, interpolation methods for transformation accuracy, and convergence monitoring for optimization stability.
