How to apply DWT & Inverse DWT for an image using lossless 5/3 lifting approach used in jpeg2000?

% I have worked on this code,but decomposition is upto one level only and also not proper.

clear all; close all; i=imread('image22.jpg'); sX=size(i); [LL,LH,HL,HH]=dwt2(i,'db1'); figure(1) subplot(2,2,1);imshow(LL);title('LL band of image'); subplot(2,2,2);imshow(LH);title('LH band of image'); subplot(2,2,3);imshow(HL);title('HL band of image'); subplot(2,2,4);imshow(HH);title('HH band of image'); X = idwt2(LL,LH,HL,HH,'db1',sX); figure(2) imshow(X,[ ]);
