Mutual Information-Based Image Registration

This is a mutual information-based image registration program featuring simple implementation and MATLAB coding. The primary objective of this program is to align two images for subsequent analysis and processing. By calculating mutual information between images, we can identify optimal registration parameters to achieve more precise alignment results. The program utilizes MATLAB's image processing toolbox, providing convenient functions and tools that simplify and accelerate the registration process. The core algorithm involves maximizing mutual information through optimization techniques like gradient descent or simplex methods, where key functions include imregister() for automated registration and mutualinfo() for similarity metric calculation. In practical applications, this program can be employed in medical image processing, remote sensing image registration, and other related fields. Consequently, this image registration program demonstrates broad application prospects and significant potential.
