title: How to divide image into same size blocks?
body: <p>I have an image and I want to divide it to same size blocks. For example image size is 16. I would like to divide my image they apply function ( such as SVD, DWT, Fourier transform ) on each block to search which blocks are similar to each other. For example I can copy one part of the image and paste it to another part of the image so blocks are similar to each other I want to search for those similar blocks.</p>
  
  <p>I am new in Matlab, I really appreciate if anybody can help me how to divide the image.
  Thanks</p>
