I don't know how it is done in pixel land but interpolating around blank
areas in the retina is the way the eyeball does it. The brain fills in the
area of the blind spot, the place where the optic nerve enters the retina,
with an image based on what the surrounding area sees. Apparently, among
humans, the technique is at least 2 million years old. So a software fix is

In memory - Land..... certain memory locations are dead due to manufacturing

defects........ so IC makers put in a few extra cells and program each

individual IC to actually work around the dead cells.....

Easier said than done in the land where pixels' locations are actually

spatially important.....
