can I apply CCA to thePCA features of two different images.

I am trying to obtain PCA features of two images of same size. My question is can i find correlation of the two PCA features using CCA.

Hello!

To find CCA (Canonical Correlation Analysis) using two PCA (Principal Component Analysis) features of two images, you need to load the desired images first into MATLAB, and then flatten those images using the “reshape” function into 1 dimensional vector.

After that, find the PCA coefficient and the score of both the images using “pca” function.

These scores can then be fed to “canoncorr” function for finding out the desired CCA result.

For more information regarding the “pca” and “canoncorr” function, kindly refer to the following MATLAB documentation:
