Displaying iamge

I have a code 

x=rand(64,64,16)

J=1;T=50;

[Faf, Fsf] = FSfarras;

     [af, sf] = dualfilt1;

     w = dualtree3D(x, J, Faf, af);

     in  w  i have 8 subbands,please tell how to display these 8 subbands of images 

for example in dwt2d

x1=imread('Tulip.jpg');
X=rgb2gray(x1);

imshow(X);

[af, sf] = farras;
x=double(x);
  J = 1;
  w = dwt2D(x,J,af);       %Performing DWT of level 1 decomposition

i display 4  subband as 

imshow(uint8(w{1,2}));

imshow(uint8(w{1,1}{1,2}))

imshow(uint8(w{1,1}{1,1}))

imshow(uint8(w{1,1}{1,3}))

please tell how to display for dualtree3d
