I haven't done the pixel-by-pixel deviation checking, but they may be comparable and independently derived!
It reminds me people who research "colorizing grayscale photos", which do not exist anymore either (if you want a color photo of someone you met in your life, there probably exists a color photo of that person).

There's a whole world of embedded devices with wide varieties of screen resolutions.
There are also several 32x32 led panels, which one could imagine needing some text.
Also, this kind of thing is just interesting, regardless of the usefulness.
* a huge corpus of historical imagery
* cheaper grayscale cameras + post processing will surely enable all sorts of uses we haven't imagined yet.
* a lower power CCD and post-processing after the fact or on a different device allows for better power budget in cheap drones (etc).
* these algorithms can likely be tuned or used as a stepping stone for ones that convert non-visible wavelengths into color images.
And that's just off the top of my head as someone who doesn't really work with that stuff. I'm sure there are plenty of other reasons I can't think of.
Also, if there are only grayscale photos of you, you were probably born before 1900, and all your friends or your children (who might want to colorize your photo) are probably dead, too.
Find me a 0.66" OLED display for ~$1 that has hundreds of pixels on each side then.

What train of thought led you to think people are primarily researching colorising new B&W photos? As opposed to historical ones, or those of relatives taken when they were young? You can take a colour photo of granddad today but most likely the photos of him in his 20s are all in black and white.
Every grayscale photo of someone famous has already been colorized during the past 50 years. If there are only grayscale photos of you, you were probably born before 1900, and all your friends or your children (who might want to colorize your photo) are probably dead, too.
Bloody hell, warn people before you post things like that.
I would have loved to have seen a sample of the 4x5, not just the 5x5.

xxHowever, 5x5 isn't enough to draw "e" properly if you also want lowercase letters to have less height than uppercase, so you need at least 6 vertical pixels. And then that isn't enough to draw any character with a descender properly, so you need at least 7 vertical pixels (technically you should have 8 in order to allow "g" and "y" to have a distinct horizontal descender while still sitting on the baseline, but this is probably an acceptable compromise). And remember that in practice this means you will still need at least 8x6 pixels to draw each character, to allow for a visible gap between letters below and beside them.
(but yeah, it's not quite right, and is especially jarring in the nice, clean, blown up pixels in the top example)
Note: there are repeat glyphs here like c and o, though the example actually uses a different c somehow. But perhaps repeats are ok given context.
Plenty of systems did it like CP/M on the Spectrum +3 and it looks pretty decent.
