Obviously, the input needs to be a suitably high-resolution image, or 
actually a set of images focusing on the different layers on the surface 
of the silicon die. says that the 6502 die 
shots were in 4,677×5,097 pixels in size. I guess that the vectorization 
might become easier when the image resolution with respect to the 
feature size is larger.
is another technique that I would expect to come into play is because to 
capture the necessary amount of detail, the microscope can only view a 
part of the silicon die at a time. So, you would stitch multiple images 
together. And I guess it is hard to get good shots when you have to move 
the decapped chip between exposures.
