error in converting 3D image into three orthogonal planes

I used the following code to convert the depth image into three planes (cartesian) which are Front, Side and Top.

    function [F,S,T] = depth_projection(X)

[rows cols D] = size(X);
X2D = reshape(X, rows*cols, D);
max_depth = max(X2D(:));

F = im2uint8(zeros(rows, cols));
S = zeros(rows, max_depth);
T = zeros(max_depth, cols);

for k = 1:D   
    front = im2uint8(X(:,:,k));
    side = zeros(rows, max_depth);
    top = zeros(max_depth, cols);
    for i = 1:rows
        for j = 1:cols
            if front(i,j) ~= 0
                side(i,front(i,j)) = j;   % side view projection (y-z projection)
                top(front(i,j),j)  = i;   % top view projection  (x-z projection)
            end
        end
    end

    if k > 1
        F = F + abs(front - front_pre);
        S = S + abs(side - side_pre);
        T = T + abs(top - top_pre);
    end   
    front_pre = front;
    side_pre  = side;
    top_pre   = top;
end

F = bounding_box(F);
S = bounding_box(S);
T = bounding_box(T);

I simply read the image and then feed it to the above function as:

currentimage = imread(currentfilename);

[F,S,T] = depth_projection(currentimage)

I have three questions to get a clear idea about:

1. Whenever I used size with the image, * D* being _ 3_. So I don't know if this is the number of channel or depth!

2. I don't why the side (S) and top (T) images being as black and white (ARE THEY BINARY) and there is some noise in. Side result example:

<<top>>

<<side>>

3. is there anything wrong in the code could be corrected.

Please any idea about the above issue?

Hi Mammo, o.k. since you ASKED, here’s a comment. The bottom line is, people here are volunteers and are free to pick and choose what to respond to (or not). There is nothing inherently wrong with choosing 'not'. As to the question itself, some aspects might have influenced the lack of comments. First, the code doesn't run, since it uses a function that was not provided. Second, the files you tried to attach to help explain the question don't seem to be there; at least I couldn't figure out how to get them. Hopefully one of the files was a small example input file to the code. Third, in my opinion it's difficult to figure out what your lead question means exactly.

@Mammo Image: Your question contains 3 dead links to images. Before I start to read the complete question, I wait until you have fixed the problem.

 1. Whenever I used size with the image, * D* being _ 3_. So I
 don't know if this is the number of channel or depth!

This is not a question. I guess you mean the line "[rows cols D] = size(X)". What do you define as "number of channel" or "depth"?

 2. I don't why the side (S) and top (T) images being as black and
 white (ARE THEY BINARY) and there is some noise in. Side result
 example:

The examples are missing. This is not a question also. Without having your inputs or seeing your outputs, there is no chance to guess, what your problem is here.

 3. is there anything wrong in the code could be corrected.

How could a reader know this?

No reason to shout. Your question does not contain enough information to be answered. This is not a problem of the forum. Please edit your question, inset the missing images and clarify the questions. Then the chances to get a useful answer will grow.
