MATLAB: How to swap bit plane??

bit plane swap

it is bitplane decomposition code..i want to swap them.. how to do it???
g=imread('girl.png');
g=rgb2gray(I_scramble);
g1=bitget(g,1);
g2=bitget(g,2);
g3=bitget(g,3);
g4=bitget(g,4);
g5=bitget(g,5);
g6=bitget(g,6);
g7=bitget(g,7);
g8=bitget(g,8);
figure,imshow(g);
title('original image');
subplot(4,4,1),imshow(logical(g1)),title('Bit 1');
subplot(4,4,2),imshow(logical(g2)),title('Bit 2');
subplot(4,4,3),imshow(logical(g3)),title('Bit 3');
subplot(4,4,4),imshow(logical(g4)),title('Bit 4');
subplot(4,4,5),imshow(logical(g5)),title('Bit 5');
subplot(4,4,6),imshow(logical(g6)),title('Bit 6');
subplot(4,4,7),imshow(logical(g7)),title('Bit 7');
subplot(4,4,8),imshow(logical(g8)),title('Bit 8');
%L=imread('monarch.png');
L=rgb2gray(I1_scramble);
L1=bitget(L,1);
L2=bitget(L,2);
L3=bitget(L,3);
L4=bitget(L,4);
L5=bitget(L,5);
L6=bitget(L,6);
L7=bitget(L,7);
L8=bitget(L,8);
figure,imshow(L);
title('original image');
subplot(4,4,1),imshow(logical(L1)),title('Bit 1');
subplot(4,4,2),imshow(logical(L2)),title('Bit 2');
subplot(4,4,3),imshow(logical(L3)),title('Bit 3');
subplot(4,4,4),imshow(logical(L4)),title('Bit 4');
subplot(4,4,5),imshow(logical(L5)),title('Bit 5');
subplot(4,4,6),imshow(logical(L6)),title('Bit 6');
subplot(4,4,7),imshow(logical(L7)),title('Bit 7');
subplot(4,4,8),imshow(logical(L8)),title('Bit 8');
how to swap this ???

Best Answer

gall = cat(3, g1, g2, g3, g4, g5, g6, g7, g8);
gall_scramble = gall(:, :, randperm(8));
gscramble = zeros(size(g));
for p = 1 : 8
  gscramble = bitset(gscramble, p, gall_scramble(:,:,p));
end
