Image registration using mutual information implemented with MATLAB. This method involves processing images through MATLAB's image processing toolbox and calculating mutual information between image pairs. The implementation typically includes key steps: image preprocessing using functions like imread and im2double, mutual information computation through entropy calculations and joint histograms, and optimization algorithms such as gradient descent or simplex method to maximize mutual information. The registration process employs transformation models (affine or rigid) using MATLAB's imtransform function, with mutual information serving as the similarity metric. This approach enables more precise image alignment by measuring statistical dependency between images, significantly improving performance in medical imaging analysis, remote sensing applications, and computer vision tasks where accurate spatial correspondence is critical.
