Instant Method to Create Stable, Realistic AI Characters with Consistent Diffusion
Are you interested in creating realistic AI characters? Do you want to know the secret to achieving consistent diffusion in image generative AI? In this video, we will introduce you to a method that can help you create stable, lifelike AI characters using stable diffusion. Whether you're starting an Instagram AI modeling account or just want to learn more about this fascinating technology, this method is sure to impress you. We will demonstrate how the consistent face generated by our realism checkpoint model can seamlessly blend with a real-life photograph, all without the need for additional editing tools. So, let's dive right in and get started!
Setting Up the Tools
Before we begin, let's make sure we have all the necessary tools for this method. We will be using the epic realism checkpoint model, which you can download from civic time.com. Once you have downloaded the model, place it in the models folder inside the stable diffusion folder. Additionally, we will need the epic realism helper Laura to enhance skin details and add imperfections. You can find the Laura file in the LAURA folder within the model's directory.
Now, let's install the required extensions. We will be using Ultimate SD Upscale and Roope. Open your automatic 1111 web UI and navigate to the extensions tab. Select "Install from your URL" and copy and paste the GitHub repository link for Ultimate SD Upscale. Click "Install" and do the same for Roope. Once both extensions are installed, it's recommended to close your web UI and restart it to ensure the extensions work correctly.
The Exciting Part: Applying the Method
Now that we have everything set up, let's get started with the exciting part. Load the epic realism checkpoint in the image-to-image section of automatic 1111. Select "Inpaint" and load the image where you want to replace the face. Focus on the face and neck during the painting process.
Keep most of the settings as they are, but change the mask padding pixels to 50. For the sampling method, choose "dpm ++ Karras" and set the sampling steps between 25 and 30. Click on the ruler icon to access the image resolution and use the aspect ratio calculator to minimize the dimensions. Aim for a width of 1024 and a height of 1536. Set the CFG scale to six and keep the noise strength between 0.40 and 0.50.
Now let's move on to Control Net. If you're new to Automatic 1111, don't worry, we have a video explaining how to install and use Control Net. In the preprocessor, choose "face only" and make sure to check "enable." Upload an independent control image and click the explosion icon to allow preview.
The next step involves using Roop, an extension for stable diffusion's Automatic 1111 that enables face replacement in images. Choose a high-quality portrait picture for the target face. Check the "enable" button and keep the other settings as they are. For the positive prompt, use a simple phrase like "raw analog style, a candid, a beautiful woman's face smiling." Keep the negative prompt simple as well, with terms like "deformed, bad anatomy, and jewelry." Click "generate" and see the magic happen as the face is seamlessly replaced.
Enhancing the Image
To make the image even better, we can upscale it and apply skin enhancement using Laura. Open a new tab for Automatic 1111 web UI and go to the PNG info tab. Load the last generated image and click "send to image-to-image." Add the Epic Realism Helper Laura and start experimenting with the intensity. Start with 0.6 and adjust as needed. For the sampling method, choose "dpm ++ Karras" again and set the sampling steps between 25 and 30. Keep the dimensions the same as before and try a CFG scale of five or 5.5. For noise strength, set a low value around 0.2 to preserve image details during upscaling.
Now let's move on to upscaling. Under the script section, choose Ultimate SD Upscale from the dropdown menu. This extension allows you to upscale using a tiles technique and works well with any video card. Select "choose from image size" and make the image twice as big. In the upscale section, choose "4X NMKD Superscale" to pair perfectly with epic realism. You can download this model from the link in the description and place it in the models folder inside the SA folder. Keep the other settings as they are and click "generate." Wait for the result and be amazed by the seamless blend of the face with the original image, along with the realistic skin texture thanks to Epic Realism Helper.
Now that we have achieved such impressive results with one image, let's try the same settings with other images and ensure consistent outcomes. Keep in mind that the replaced face may look familiar but might not be 100% identical to our target. Factors like the original face shape, pose, and lighting conditions can affect the outcome. Experiment, have fun, and explore the possibilities of this amazing method!
Conclusion
In conclusion, creating stable, realistic AI characters with consistent diffusion is now within reach. Thanks to the epic realism checkpoint model, extensions like Ultimate SD Upscale and Roope, and the help of Laura, we can seamlessly replace faces in images and enhance them with lifelike details. This method opens up exciting possibilities for AI modeling, photo editing, and artistic expression. Give it a try and witness the power of image generative AI!
