Takeaways
- 🎨 Use ControlNet in Stable Fusion to manipulate faces and poses in generated images.
- 📌 Select the appropriate preprocessor for faces, such as 'Face' or 'Face Only', to control the pose and direction.
- 🔍 The 'Face Only' option allows the body to take any shape, while 'Face' restricts the body to match the pose.
- 📈 Start with ControlNet version 1.1 for portrait images and use Stable Fusion 1.5 models.
- 🔧 Adjust the control steps from 0 to 1 to fine-tune the level of control over the generated images.
- 🚫 Negative styles can be used to correct issues like teeth misalignment in the generated faces.
- ✅ Prompting the AI with specific actions (e.g., 'woman shouting') can help achieve the desired output even if not visible in the control image.
- 🔄 Combining prompts with styles like 'digital oil painting' can enhance the quality and style of the generated images.
- 🧩 Changing the ending control step can introduce variations while maintaining a base style for the generated images.
- 👽 For full character images, use 'Open Pose Full' to control the entire character's pose, including hands.
- ✍️ If faces are not generated correctly, use the inpainting tool to manually correct them for better results.
- 🤖 Mediapipe Face is an alternative to ControlNet 1.1, offering more detailed control around the eyes and mouth.
Q & A
What is the main topic of the tutorial?
-The main topic of the tutorial is how to control faces inside of stable Fusion using ControlNet.
What are the two preprocessor options available for faces in ControlNet?
-The two preprocessor options available for faces in ControlNet are 'face' and 'face only'.
What happens when you use the 'face only' preprocessor option?
-When you use the 'face only' preprocessor option, the body can take any shape around the face, whereas with the 'face' option, the body is restricted to having the same pose as indicated by the lines in the preprocessor.
What is the purpose of using negative styles in the generation process?
-Negative styles are used to fix issues encountered in the generated images, such as incorrect facial features, by providing the AI with additional information to guide the image generation.
How can you prompt the AI to generate images with specific facial expressions?
-You can prompt the AI to generate images with specific facial expressions by including descriptive text in the prompt, such as 'woman shouting', which tells the AI to generate images with the woman's mouth open.
What is the difference between using the 'full' and 'face only' models in ControlNet?
-The 'full' model generates a full body with the face, while the 'face only' model focuses solely on the face, allowing the body to take any shape around it. The choice depends on whether you want the body's pose to be controlled or not.
What is the role of the 'control weighted' parameter in the ControlNet?
-The 'control weighted' parameter determines the influence of the ControlNet on the image generation. Starting the control at 0 and ending at 1 means that the AI will gradually increase the control from no influence to full influence over the course of the render.
How can you introduce variations into the generated images?
-You can introduce variations into the generated images by changing the ending control step, which alters the degree of control exerted by the ControlNet, allowing for more randomness or 'chaos' in the final output.
What is the significance of using the 'open pose' model in ControlNet?
-The 'open pose' model in ControlNet is particularly useful when you want to change the style of the generated images, as it allows for more flexibility in the body's pose and can handle different styles effectively.
How can you fix facial features that are not generated correctly?
-You can fix facial features that are not generated correctly by using the 'between painting' feature, which allows you to manually edit the face and instructs the AI to fill in the rest of the image with new material while keeping the original content intact.
What is the Mediapipe face model, and how does it differ from the ControlNet 1.1 face models?
-The Mediapipe face model is a separate face detection model that provides more detailed information around the eyes, eyebrows, and mouth compared to the ControlNet 1.1 face models. It offers an alternative option for users to achieve better results based on their specific needs.

😀 Introduction to Controlling Faces in Stable Fusion
The speaker begins by introducing the audience to the process of controlling faces within Stable Fusion, a tool that allows for the manipulation of facial features in images. They demonstrate how an input image can be transformed into various output results with the help of a control net. The tutorial also suggests installing necessary components if not already done, and provides a link to a previous video for guidance. A practical demonstration is given where an image of a woman shouting is used to explain the use of the face-only preprocessor option in Control Net, which allows for the control of facial features such as the mouth, nose, and eyes. The difference between 'face' and 'face only' preprocessor options is explained, highlighting how they affect the body's pose in the final image. The speaker also mentions the use of Control Version 1.1 with Stable Fusion 1.5 models and provides troubleshooting tips for common issues encountered with the face preprocessor.
🎨 Advanced Techniques for Control Net Image Generation
The paragraph delves into advanced techniques for generating images using Control Net. The speaker discusses the use of 'negative styles' to improve image quality and correct common issues like distorted teeth. They also explain how to prompt the AI for specific poses or actions not captured in the control image by adding descriptive text, as demonstrated with the example of a woman shouting. The paragraph further explores the use of different models and settings within Stable Fusion to achieve desired outcomes, such as using the 'open pose face only' model to allow for more variation in the body's pose while maintaining the face's pose. The speaker also touches on the process of generating images with variations by adjusting the control step settings, providing examples of how this can introduce a degree of randomness to the image generation process.
🚀 Exploring Open Pose and Media Pipe Face Models in Control Net
The final paragraph focuses on the use of the Open Pose model for full character images and the Media Pipe Face model as alternative options within Control Net. The speaker explains that Open Pose is particularly effective for changing styles and maintaining the integrity of the character's pose, even when faces are not clearly visible in the original image. They also demonstrate how to correct facial features that do not render well by using the 'digital painting' feature to manually adjust the face. The Media Pipe Face model is introduced as an alternative to Control Net's face models, offering more detailed control around the eyes, eyebrows, and mouth. The speaker encourages viewers to test different options to find the best fit for their specific needs and concludes with a reminder to subscribe for more content.
