I have an image that I am suppose to `Half' the size of the image (i.e. reducing it to 256x256) by extracting only even numbered elements. This is my code so far:
% Part i.
imgroup1=imresize(A1, [512 512]);
% Part ii.
But i dont understand how mod will help me 'extract' the even numbers from the image or how i would display it afterwards. Can someone explain?
