Block Division using cell

Using cell data type one can effectively breaks the 2D/3D data in to required no. of blocks.

Description

Two functions are provided; one to break the data in blocks and another one to recombine them in proper order.
- Code given can break any 2d image into 8*8 blocks and put them in a cell. For ex. function assumes the input image of size 512x512 and it will break this image in to 4096 blocks of 8x8 elements each.
- One can perform desired operation on each block individually like watermarking, enhancement etc.
- After processing second function accept 4096 blocks (a single cell) as input and gives back original image back.

• Required Products: MATLAB
• MATLAB release: MATLAB 7.13 (R2011b)

See imsplit (File ID: #40173) for more options.

Also, cell2mat should be an faster way to glue the blocks back together.
