Hi, I have a basic image processing question. I am dealing with two sets of images. Lets say image A (average of 10 image sets) and image B (average of 10 image sets). How do I do the average of 10 images to get image A and B and then subtract image A from image B. Many thanks for any leads.

For example,
setA=rand(256,256,10);
setB=rand(256,256,10);
imageA=mean(setA,3);
imageB=mean(setB,3);
result = imageB-imageA;

what does 3 mean in mean (setA, 3).
It means take mean of all the slices setA(:,:,i).
Also i am reading the images from some file. I am not sure, how would i implement this code.
Read the images into an MxNx10 array, e.g., by doing,
setA(:,:,i)=imread(___);
