Transferring multiple features via single function in one go..

i am trying to extract features from an image and using classification algo,trying to find out the best features among all extracted features. in my case, i have extracted features from images,say,8,stored in same folder with distinct names

i need to pass all those features together to a function that would try to classify them for best feature out of total 8, and give me output.i am not finding any way to send all extracted features in one go.right now,i am able to send individual features but they dont solve my purpose......

any help would be highly appreciated (if possible,in form of code with explanation).

thank you
