How to use PCA loading and score for image classification?

03 March 2018 0 9K Report

I have an image obtained from a scan with hyperspectral camera. The image represents 4 different object. From the image i can extract 4 different matrix, relative to the 4 object. Every matrix is composed of the spectra of the samples. I can apply PCA analysis on the concatenated matrix in order to obtain the score and loading of the data. Once i obtained the loading and score how i can re-plot the image respect the different loading? i sufficient to multiply the image for the respective loading?
