Grey background and other tips for best results
I've been experimenting with node setups to push this model further and had an additional question about having good foundations to get optimal results with this.
The grey background (#808080) you mentioned in the model card. Is that meant as a replacement for the non-module palette color (normally white) for the QR that is fed into the controlnet input, or is that a color to use for any area outside the square bounds of the entire code?
Since the training process does not have much info, the current description leaves some ambiguity. I do know from small tests that if I make a dual color QR with #000000 and #808080 in a simple setup without using a qr img to img starting point, it won't be scannable even when cranking up the controlnet strength to 10. But it works fine with the #FFFFFFF non module color.
Was my initial interpretation completely wrong (and the input should consist of white+black and grey on the outside) or was it a recommendation to enhance greater QR contrast flexibility (with the assumption that img2img will also be used)?
It is in fact gray on the outside, here an example I gave on civitai:
Sorry for the ambiguity 😶
No plans for 2.1, but I'm in the process of making a XL version.
The 768x768 images are made with 1.5, it works well.
YEAH !!! very XooL
