I am using DWT in my code. After, applying DWT on an image, i get the resultant image as shown in attached figure (DWT output).
Now i want the LL part to be displayed alone in the full image area as shown in figure attached (required output), means black portion (as shown in the DWT OUTOUT IMAGE) should not be visible, instead the LL part should cover that portion.

What function did you call? Doesn't dwt2() give you all 4 as separate output arrays?

A = imread('yourfile.jpg');
[n,m,~]=size(A);
B=A(1:fix(n/2),1:fix(m/2),:);
imshow(B)
