I has nothing to do with it. Unfortunately, OP is engaging in a cheap form of terminology hijacking.
Either that or OP has no idea what the word 'photorealism' means.
Either way OP is doing himself a disservice. Great project. Siraj-Raval vibes.
That might be true. What would you suggest as a better description.
"Picture to QR code converter"?
It uses dithering by Spacial Colour Quantification to get the best photorealistic 93x93/186x186 colour image. The title plays on that the QR can be near photo and not some pixelated icon.
