⚙️ Prerequisites

1. Download this repository and open AI-QRCode.ipynb with Google Colab.
2. Open Resources and set the Hardware accelerator to GPU.

🕸️ Open WebUI

Follow the steps in the code to open the Public URL.

Navigate to Settings and ControlNet. Make sure Multi ControlNet: Max models amount is set to more than 2 (default is 3), then click Apply settings and Reload UI.

🎨 QR Code Generation

Follow the steps below to generate your QR code Art:

1. Open ControlNet -> ControlNet Unit 0 and upload your QRCode.
2. Adjust your settings as follows:
   • set the preprocessor to [invert] if your image has a white background and black lines to Enable
   • Set Preprocessor to inpaint_global_harmonious.
   • Set Model to control_v1p_sd15_brightness [5f6aa6ed].
   • Set Control Weight to 0.35.
3. Open ControlNet -> ControlNet Unit 1 and upload your QRCode, then adjust your settings as follows:
   • set the preprocessor to [invert] if your image has a white background and black lines to Enable
   • Set Preprocessor to inpaint_global_harmonious.
   • Set Model to control_v11f1e_sd15_tile [a371b31b].
   • Set Control Weight to 0.55.
   • Set Starting Control Step to 0.35.
   • Set Ending Control Step to 0.75.
4. Prompt your QR Code image to be generated. For instance:
   • Prompt: masterpiece, best quality, Japanese house, tree, and city background
   • Nagative Prompt: UnrealisticDream, FastNegativeEmbedding

📌 Others

The style of the generated image heavily depends on the Stable Diffusion checkpoint. You can change the checkpoint to generate a QR code image with a different style.

You can add more checkpoints by modifying these lines of code:

To download checkpoints, run curl -Lo filename.safetensors downloadLink and move the downloaded file into the /content/microsoftexcel/models/Stable-diffusion folder.
