Hey guys, So I have to crop a bunch of loaded in images without using imresize or imcrop to dimensions 120x129. I also have to plot all of the images onto a single figure. Ive tried a few things and nothing seems to work. This is the code I used to load in all of the images
imageFiles= dir('*.jpg')
nFiles=length(imageFiles)
iWant=cell(nFiles,1)
for ii=1:nFiles
iWant{ii}=imread(imageFiles(ii).name)
end

imcrop() works by indexing parts of the array. imcrop(A, [x y width height]) is
A(y:y+height-1, x:x+width-1, :)
There are multiple ways to resize images. One of them involves fft2(). One of them involves interp2(). One of them involves wavelets. There are other ways.
