Detailed Documentation
This document introduces functions designed for image alignment through rotation and translation operations. The image_registr_MI.m function implements mutual information-based image registration, which optimizes alignment by maximizing the statistical dependency between images. The MI2 function specifically calculates mutual information values, typically using probability distributions derived from image intensities. Additionally, the joint_h function computes joint histograms, which serve as fundamental components for mutual information calculation by quantifying the co-occurrence statistics of pixel values between image pairs. These functions enable precise image alignment, thereby enhancing accuracy and efficiency in image processing workflows. The implementation likely involves optimization algorithms (such as gradient descent) for parameter search and may include interpolation methods for handling rotational transformations.
