MATLAB: How to divide a image into cells and naming the cells with numbers. then transformed the cells in the image to transform the image….can anyone pls give me a code for this

If you mean "cells" as in the MATLAB cell array data type, then this might be what you need

http://www.mathworks.com/matlabcentral/fileexchange/35085-split-nd-array-into-equal-sized-cells

E.g.,

   >> Image=rand(64); ImageCells=mat2tiles(Image,[16,16])
ImageCells = 
      [16x16 double]    [16x16 double]    [16x16 double]    [16x16 double]
      [16x16 double]    [16x16 double]    [16x16 double]    [16x16 double]
      [16x16 double]    [16x16 double]    [16x16 double]    [16x16 double]
      [16x16 double]    [16x16 double]    [16x16 double]    [16x16 double]
