I have a coarse grid of size say 5x5, which I call Grid System-1, and I want to further subdivide that grid system in three steps as:

Grid System-2: Each grid of Grid System-1 is subdivided into 5x5 with 625 total grids

Grid System-3: Each grid of Grid System-2 is subdivided into 5x5 with 15625 total grids

Grid System-4: Each grid of Grid System-3 is subdivided into 5x5 with 390625 total grids

In all the above steps the boundary size of all the Grid Systems is similar (say 1m X 1m)because we are only increasing the fineness of each grid by further subdividing it. Can someone help implement this in Matlab? Thanks!

    See my [answer](http://stackoverflow.com/questions/12520152/resizing-3d-matrix-image-in-matlab/12521482#12521482) to another question. – chaohuang Nov 12 '12 at 05:10
  • That function `resize()` from *kWave* toolbox is useful and a related google search led me to essentially similar `imresize()` function in Matlab. It would be helpful if I could change the interpolation method to some custom method. –  Nov 12 '12 at 22:14

Check out this Coarse-to-Fine Image Reconstruction toolbox from the guys at Duke. It may be the thing you're after.
