A QR code, known as Quick Response code, is a type of image that contains encoded information, including text or URLs. By utilizing a smartphone's camera, these codes can be scanned, granting immediate access to the content they encode. QR codes have gained widespread popularity across different fields, ranging from marketing initiatives to contactless transactions. Discover how to create amzing looking QR codes by harnessing the power of Stable Diffusion and ControlNet.
To create QR codes with Stable Diffusion, we will utilize the AUTOMATIC1111 Stable Diffusion GUI.
Make sure you have the following installed to create stunning QR codes:
Once you have downloaded the right models using the provided links, you can simply move them to your ControlNet models folder. stable-diffusion-webui\extensions\sd-webui-controlnet\models These will be necessary for our QR code generation process.
Before proceeding with Stable Diffusion, you need a QR code that meets certain criteria for better results. Ensure that the QR code:
Use a Free QR Code Generator to meet the above criteria.
Using the website above we created the following QR code, which leads to our website:
After successfully generating a QR Code you can you can download the QR code as a PNG file.
The process of creating stunning QR codes involves using Stable Diffusion's txt2img function alongside the 2 ControlNet models. By generating a random image, we lay the foundation. However, to produce a valid QR code, we utilize the two ControlNet models download before during the sampling steps. Towards the end of the sampling process, ControlNet is turned off to enhance the image's consistency.
Now the basic settings are set up we move to the a little more advanced ControlNet settings. Make sure you have at least 2 ControlNet Units available, if you only have 1 go to the Stable Diffusion settings tab, click on ControlNet and set Multi ControlNet to at least 2. Apply the settings and press on Reload UI.
Now you should have at least 2 ControlNet Units available, upload your QR Code to both the ControlNet units. In the first ControlNet Unit (ControlNet Unit 0) select inpaint_global_harmonious as the Preproccesor, for our Model we will use control_v1p_sd15_brightness. Set the Control Weight to 0,5 and the Ending Control Step to 0,75. You can leave the rest as it is.
In the second ControlNet Unit (ControlNet Unit 1) select inpaint_global_harmonious as the Preproccesor, for our Model we will use control_v11p_sd15_lineart. Set the Control Weight to 0,35 and the Ending Control Step to 0,75. You can leave the rest as it is.
Make sure both ControlNet Units are enabled. I also recommend checking the Low VRAM box in both the ControlNet Units, this is not necessary if you have a 16GB GPU or higher.
Now you're all set to generate you awesome looking QR Codes!
Keep in mind that there is not a 100% success rate, some codes will scan better than others. If you're having trouble getting your QR Code to scan try these tips:
In conclusion, Stable Diffusion unlocks a new realm of creativity for QR codes. By following the step-by-step guide and experimenting with different prompts, we can generate visually stunning QR codes that merge artistry and functionality. With the right parameters and adjustments, QR codes can become captivating visual pieces. Embrace the potential of Stable Diffusion and QR codes to create remarkable and memorable experiences in visual communication.
