How to convert the digit image into (3*2) blocks where I can check vertical and horizontal edges ? Actually, I need to check if vertical or horizontal edges exists in each block? If exists I need to return binary value 1.

在 MATLAB Online 中打开

A = imread('image 2.png') ;
m = 3 ; n = 2 ;
[nx,ny] = size(A) ;
if mod(nx,3)
    nx = nx+(3-mod(nx,3)) ;
end
if mod(ny,2)
    ny = ny+(2-mod(ny,2)) ;
end
A = imresize(A,[nx ny]) ;
l = size (A) ./ [m n];
T = mat2cell (A, repmat (m, l(1), 1), repmat (n, l (2), 1))

Suppose, I resized the digit image into (64*64). Then I need to convert it into (3*2), total 6 blocks. Then I need to check whether there is a horizontal or vertical edge in each block?
