How do you measure the image size? Is it the produced file size?
Can you add a

   output->Print(std::cout);

in your program, where output is the image produced filter, and post  
the result here? It would let us check the pixel type used.

Maybe because fo the rescale performed on a 16-bit images by your  
viewer?

The images used in the tests looks like what I would expect from this  
kind of filter:
