MATLAB code for performing Canonical Correlation Analysis between two images, with input parameters: input image 1, input image 2, rows, columns, channel 1, channel 2, and output matrix. The implementation involves preprocessing, feature extraction, and correlation computation using canonical correlation algorithms.

Application Background For a long time, there has been a clear distinction between model-based methods and epistemological approaches. Partial Least Squares (PLS) organically integrates these two methodologies, enabling simultaneous implementation of regression modeling (multivariate linear regression), data structure simplification (principal component analysis), and correlation analysis between two variable sets (canonical correlation analysis) within a single algorithm. This represents a significant breakthrough in multivariate statistical data analysis. Key Technology As a multivariate linear regression method, the primary objective of PLS regression is to establish a linear model: Y=XB+E, where Y is the response matrix with m variables and n sample points, X is the predictor matrix with p variables and n sample points, B is the regression coefficient matrix, and E represents the noise correction model with the same dimensions as Y. Typically, variables X and Y are standardized before computation by subtracting their means and dividing by standard deviations.
