divide image into overlapping blocks

Hi, Can anybody tell me how to divide an image into overlapping blocks and apply svd to each block. Any help in this regard is highly appreciated. This is my code snippet.

L = 1;
fu = @(block_struct) svd(block_struct.data);
J = blockproc(LL{L}, [16 16], fu);

When i run this i dont get error but the "J" do not satisfy (M-B+1)X(N-B+1). Anybody if knows how to do it can share his view. Thanks in advance.
