Is there a mistake in my syntax using blocproc:
Binary1=blockproc(OrigImage,[tileRowSize, tileColSize],@(x) myOperation(hObject, eventdata, handles, x.data));
the function I use "myOperation" is as follows:
function myOperation(hObject, eventdata, handles,tile)
[thresh1, thresh2] = Threshold(hObject, eventdata, handles,tile); %my personal thresholding function
%Create Binary Image
size(tile)
ix=tile;
level=thresh2
ix(ix<level)=0;
ix(ix>level+1)=1;
Im getting
Binary1 =

I don't have time to look at it now, but in the meantime, see my blockproc demos, attached.

What does your "myfunction" function output? It looks like it's not producing any output.

If you have blocks of 25 pixels by 25 pixels, and you move in "jumps" of 25 pixels, then I believe your last block will have only 1 row or column. Thus it may not have a value like the others that had a full block in them.
