I need you to say clearly that you want to overwrite parts of the binary image, or that you want to conceptually break the image up into parts without actually changing the image.

You can use padarray() to add any number of rows or columns to any side.

bw = ones(3, 5)
% Add one row to the top, 2 rows to the bottom,
% 3 columns to the left, and 4 columns to the right
bw2 = padarray(bw, [1, 3]);
bw2(6,12) = 0
And get this:
bw =
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
bw2 =
0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 1 1 1 1 1 0 0 0 0
0 0 0 1 1 1 1 1 0 0 0 0
0 0 0 1 1 1 1 1 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0
