These are the jigsaw pieces, or pixels, which were rejected by conceptual glitches in the process, leaving dead pixels/empty spaces in the images.

Left to right: (first number is original jigsaw number 1-6, followed by grid position.  Letter = y axis, Number = x axis.)

2B36 from #2;  1B20 & 5X6 from #3;  6X5 from #4;  6B36 from #5

They are discrete pieces of information which never arrived at their intended destination.  In a digital process, they would have disappeared off into the ether, but these physical pieces are trapped in purgatory (my wallet).

I’m not sure what to do with them.
