Introduction

In this article, we will explore the fascinating world of generating artistic QR codes using stable diffusion and control net models. Originally posted on Reddit by a user on the stable diffusion forum, this technique has gained popularity and is now being widely discussed. We will walk through the entire process, step by step, using various tools and custom models. Let's dive in and learn how to Create visually appealing and functional QR codes.

What is Stable Diffusion?

Stable diffusion is a technique that utilizes diffuser models to generate images. It involves using a stable diffusion web UI provided by Automatic101 to simplify the process. With a one-click installer available for various operating systems, stable diffusion enables easy installation and model downloads. It eliminates the need for complex command-line coding, making it accessible to users of all levels of expertise.

Control Net: A Guide to Generating Images

Control net is a neural network that guides stable diffusion and diffuser models to generate images based on predefined inputs. There are two types of control nets we will focus on: tile-based and depth-based control nets. The tile-based control net allows for more control over the output, closely resembling the defined design cues. On the other HAND, the depth-based control net considers the depth mapping of the image to guide its generation.

Installing Stable Diffusion Web UI and Control Net

To get started, we need to install the stable diffusion web UI and control net. Automatic101 provides a simple and straightforward installation process for stable diffusion. Additionally, there is a control net extension available, specifically designed for the web UI. Following the installation instructions provided by Auto101 and Stable Diffusion Art, we can set up both tools on our system.

Choosing the Right Model: Ghost Mix vs Default Model

While stable diffusion comes with default models suitable for various types of image generation, we will explore an open-source model called Ghost Mix. Ghost Mix is trained or fine-tuned to generate animated and non-photorealistic images, perfect for creating unique QR codes with an artistic touch. However, if You prefer more photorealistic QR codes, the default model can also be used. The choice between the models depends on your personal preferences and the desired image generation style.

Generating a Basic QR Code

To begin, let's generate a simple QR code using a reliable QR code generator like 34qr.com. It is recommended to choose a generator that creates QR codes with white borders, allowing for better fault tolerance. A smaller QR code with high fault tolerance is preferable, as it reduces the chance of interference from other images. We can use this QR code as a starting point for further experimentation.

Using Control Net for Design Cues

Control net can be leveraged to generate design cues for our QR codes. The text-to-image functionality within the stable diffusion web UI can help us create base images or design cues to prompt the image generation process. While this step is not necessary if you already have a specific image in mind, it provides a starting point for customizing your QR code design cues.

Tile Based Control Net vs Depth Based Control Net

There are significant differences between tile-based and depth-based control nets. Tile-based control net tiles the provided image on top of the generated QR code, ensuring a more controlled output. Alternatively, depth-based control net considers the depth mapping of the image, resulting in a QR code that reflects the depth cues of a selected image. We will explore both options and their impact on the final QR code design.

Fine-tuning the Control Net Parameters

To achieve the desired image output, it is crucial to fine-tune the control net parameters. We will adjust the control weight, starting control step, ending control step, base image, sampling steps, and denoising strength. These parameters play a crucial role in guiding the stable diffusion and control net to generate QR codes that Align with our design cues. Iterating through different parameter combinations might be necessary to achieve the desired results.

Increasing Denoising Strength for Artistic Results

To add a more artistic touch to our QR codes, we can increase the denoising strength. Higher denoising strength encourages the generation of more creative and abstract QR code designs. However, it's important to find the right balance, as excessively high denoising strength may affect the readability and scanning capability of the QR code. We'll explore different denoising strength levels and their impact on the final QR code output.

Masking and Inpainting for Image Manipulation

Inpainting is a powerful technique that allows us to mask out certain parts of the image and let the stable diffusion process fill in the missing areas. By utilizing inpainting alongside stable diffusion and control net, we can manipulate and tweak the generated QR codes to align with our desired visual aesthetic. This provides additional flexibility in design and allows for more creative QR code variations.

Adjusting Denoising Strength for QR Code Accuracy

While increasing denoising strength enhances artistic results, it may impact the accuracy of QR code scanning. To ensure QR codes remain scannable, it is crucial to adjust the denoising strength accordingly. If the QR code becomes less readable, reducing the denoising strength can improve accuracy. Alternatively, increasing the weightage of the tile-based control net can emphasize the QR code's prominence. Achieving the right balance is essential to maintain both visual appeal and functionality.

Examples of QR Codes Generated Using Stable Diffusion

Throughout our exploration of stable diffusion and control net, we will showcase various examples of QR codes generated using this technique. From simple QR codes to more elaborate designs, these examples demonstrate the versatility and creativity achievable through stable diffusion. Each QR code serves as a unique and functional piece of artwork, showcasing the limitless possibilities of this innovative approach.
