How to combine separate label matrix into one

Hello...

I have three binary masks from which I generated their individual label matrix. But I can't figure out how to combine them into one single label matrix to show the three objects. The code I use for generating the lable matrix is:

    L1 = bwlabeln(BW1);
    L2 = bwlabeln(BW2);
    L3 = bwlabeln(BW3);
    
    L1((L1 > 0)) = 1; L2((L2 > 0)) = 2; L3((L3 > 0)) = 3;
    

I then use the code below to combine the three label matrix.

    L_matrix = (uint8(L1)|uint8(L2)|uint(L3));
    figure,imshow(L_matrix)
    

But the result only shows one object (all ones instead of 1s, 2s, and 3s). Attached are the masks and the resulting L_matrix.

You're looking for bitor, not logical or which only returns T|F (1|0)

BTW, you missed an '8' in the last cast expression above.

Tried it, and it worked. Thanks!
