Please help me ..

i want to make feature extraction using PCA ,using matlab code on galaxy image like that >>

I was wondering if anyone could help me with a few steps or even code to make feature extraction from images .

I would like to extract the features of galaxy images and then classify them in the classification learner app.

The data I have is a set of galaxy imagse.

The aim is to extract the features and then compare them in the classification app with each other.

Any help is appreciated!

i want to know how pca work ? does it work in gray images only ??

Thanks ..
