MATLAB: How to extract each connected object in a 3D array

Question

I have a 3D array (attached as Y.mat) and I find the connected components using bwconncomp. I used the following coding to extract each component but X is a zero array with the same size as Y. Please, help me to solve this problem.

Thanks

May

CC = bwconncomp(Y, 26); % Y is the 3D array
L = labelmatrix(CC);
for i=1:length(CC.PixelIdxList)
X = (L==i);
imshow3D(a); % use existing function to show 3D
end

Answer 1

Use ismember

oneBlobOnly = ismember(L, i);
