Hello everyone, i want to perform split in several parts of an image using blockproc () and then i want to access these blocks to perform Box Counting Algorithm. If i use
I=~I2bw(I)
blockSize=64
T=blockproc(I, blockSize, @boxcountingmethod);
My response from Matlab is a matrix with BoxCounting applied on the full image, not on every block.
Also i need to store the results in a matrix. Thanks in advance.

Using MAT2TILES (Download),
Tcell=mat2tiles(I, blocksize*[1,1]);
result=cellfun(@boxcountingmethod, Tcell, 'uni',0);

Thanks a lot Mr., but the result is the same in every row
result =

That's got nothing to do with me. Your @boxcountingmethod are producing those numbers.

Yes, this algorithm calculate Haussdorff Dimension on entire image. What i want is to divide image into blocks (i.e 64x64 )after that i need to perform in each block boxcounting. Hope you understand my question. The result may be a matrix with the values of BoxCounting not a cell array. Thanks in advance.

Yep. I've understood from the beginning. The code I gave you is applying your function boxcountingmethod() to every 64x64 block. Why this gives the same result for every block is not for me to say, because I didn't implement boxcountingmethod() nor do I have your input image. Rest assured however, it is being applied block-by-block.
If you want to convert the result to a matrix, you can use cell2mat,
result=cell2mat(result);

Constantin comented:
Thank you very much, I had a code problem. Now they are returning different values for each processed block.
