how to breaks image in to pixel

infilename = 'C:/Users/DELL/Downloads/brains1.png';
Height=8; width=8;
currentimage = imread(infilename);
[r,c,~]=size( currentimage );
[~, currentfilename, ~] = fileparts(infilename);
for i=0:Height:r
    ridx = floor(i/Height) + 1;
    for j=0:width:c
        cidx = floor(j/width) + 1;
        if((i+Height)<r && (j+width)<c)
            Image=imcrop(currentimage ,[(i+1) (j+1) Height width]);
            outfilename = sprintf('%s_%03d_%03d.tif', currentfilename, ridx, cidx);
            imwrite(Image, outfilename);
        end
    end
end

Error in p8 (line 11)

Image=imcrop(currentimage ,[(i+1) (j+1) Height width]);

Specify the error.

After looking at your code, I feel you should read about blocproc.

'imcrop' requires Image Processing Toolbox.

Instead of imcrop() you can use indexing:

Image= currentimage((j+1) : (j+Height), (i+1) : (i+width));
