How to do matching of 2 images using pca?

I tried sum of absolute differences method and pca also for matching. I took 10 images of each hand gesture and stored the images as a database after doing segmentation on them. But still my test image isn't matching correctly with the images in the database. I even don't have clear knowledge on pca. Please help me for the understanding the same.

Try to figure out your code follows same procedure as the one in this link https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&sqi=2&ved=0ahUKEwjUu_TY2_DRAhULgI8KHQO_B_oQFggZMAA&url=http%253A%252F%252Fwww.mathworks.in%252Fmatlabcentral%252Ffileexchange%252F45750-face-recognition-using-pca&usg=AFQjCNGSKpPVbSixxbJEhF8Yq-qwm2hpDQ&sig2=caGZtxJx2-39qXqk1Z3I0w&bvm=bv.146073913,d.c2I

And also PCA is not only algorithm for classification try out fishers linear discrimination and many more.
