The union of 2 images

Let's say I have an image called A and another constant image of the same size how do I get the set union of those 2 images : the union should be of the same size as image A
Note: when I use union function it gives me an error (A and B must be vectors or 'rows' must be specified.)

the union should be of the same size as image A
Then you have an unconventional definition of a "union". There's no reason they should be the same size. Possibly you want to do a pixel-wise or() operation?
Union = A|B
Otherwise please clarify.

Maybe you mean something like this:
% Find dark pixels.
binaryImage = skeletonImage < 50; % Or whatever intensity you want.
% Replace dark pixels with pixels from image B.
C_Image = skeletonImage; % Initialize
C_Image(binaryImage) = B_Image(binaryImage); % Replace.
