<p><strong>Feedback is welcome! I'm still improving this model and you can help me by generating </strong><a target="_blank" rel="ugc" href="https://civarchive.com/api/download/attachments/185"><strong>simple usecases</strong></a><strong> and discuss the results. ControlNet training alone is enough work for one person already :)</strong></p><p><strong>Update: I created a </strong><a rel="ugc" href="https://civarchive.com/bounties/28"><strong>buzz bounty</strong></a><strong> for using my ControlNet!</strong></p><h1 id="heading-2385">Summary</h1><p>Generate images which are controlled for light and dark areas by using white-gray-black control images. I didn't want to create yet another QR Code model to compete with Monster Labs model which is already great. My idea was to focus more on natural and organic images for squint illusions as opposed to QR codes and take more regard to human perception as opposed to how cameras interpret contrast. You should notice a white color in the condition image become more of a light-color (HSV) instead of THE white-color (RGB). I also found the Monster Labs model tends to produce images with higher contrast, probably to make it work better with QR codes. While this model is able to produce scannable QR codes it was not the goal.</p><h1 id="heading-2387">Usage</h1><p>Use it by setting <code>strength=0.6-0.8</code> and <code>start_percent=0-0.1</code>, <code>end_percent=0.6-1.0</code> depending on your image concept. I generally found that you have to use lower ControlNet strength compared to other QR code models. Make a XYZ-plot with different start, end and weight strengths to get an idea how it influences the generation. You also don't have to use white-gray-black images but can use grayscale or RGB images as well. I also found that fine-tuned models produce more artistic results.</p><h1 id="heading-231">Templates</h1><p>I have made a <a target="_blank" rel="ugc" href="https://civarchive.com/api/download/attachments/185">collection of different templates</a> which you can download to get started:</p><p></p><p><img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/97fb48ab-e2f5-44c0-9a06-a76ed96e4432/width=525/97fb48ab-e2f5-44c0-9a06-a76ed96e4432.jpeg" /></p><p></p><p><a target="_blank" rel="ugc" href="https://civarchive.com/api/download/attachments/185">Download here!</a></p><h1 id="heading-2386">Training</h1><p><strong>See my article </strong><a target="_blank" rel="ugc" href="https://civarchive.com/articles/2078"><strong>Play in Control - ControlNet Training Setup Guide</strong></a><strong> if you want to train your own control net!</strong></p><p>The model was trained on the laion2b-en-aesthetics65 by converting images to grayscale using HSV method, Gaussian blur with kernel=15 and remapping colors to 33% white-gray-black.
