I have already extracted multiple features like color, texture, shape extracted using methods and algorithms like regionprops, color moments, glcm, vein feature and so on. I have 110 features per image. kindly guide me how to form feature vectorization and use pca for feature reduction.
thnx

Basically you've asked us to give you a course in Image Processing in an Answers forum posting. So here it is : http://szeliski.org/Book/
I'm also attaching my pca demo, actually given to me by the Mathworks.

It is not required that you normalize features. However, normalizing features might give you much better results. Why not try it both ways?
