Hi everyone, any help on this will be highly appreciated!!

i have 3D image. Here is my program:

T=imread('....'); %host image

M=imresize(T,[400 400]);

I=im2double(M);

figure(1),imshow(I);

title('Host Image','color','b');

HSV=rgb2hsv(I);

%separate host image into H S & V components

H_plane=HSV(:,:,1);

S_plane=HSV(:,:,2);

V_plane=HSV(:,:,3);

%combine H S & V component

I1(:,:,1)=H_plane;

I1(:,:,2)=S_plane;

I1(:,:,3)=V_plane1;

figure(3),imshow(I1);

When I run the program, the error "subscripted assignment dimension mismatch" will show up, I really dont know how resolve it. I want I1 dimension should be [400 400 3]

It would be so much easier to help you if you'd shown the complete error message, particularly the bit that tells you which line the error occurs on.

As a guess, the error occurs on

I1(:, :, 1) = H_plane;

because I1 already exists and is not the same size as HSV. So,

I1 = zeros(size(HSV));

before the previous line should solve it.

------

However, I don't particularly see the point of separating the three components to recombine exactly the same way. In the end, your code is equivalent to

I1 = HSV;
