Best Way to Use LoRA (LoRA + ADetailer Face Swap)
TLDRIn this tutorial, learn how to create hyper-realistic face swaps using LoRA and ADetailer. The video demonstrates the process of training a LoRA model on Scarlet Johansson's facial features and then using ADetailer to swap her face onto full-body images. The guide covers uploading images, selecting base models, adjusting settings, and fine-tuning the face swap for seamless integration. ADetailer's ability to work with both image-to-image and text-to-image modes is highlighted, offering flexibility in creating realistic face swaps.
Takeaways
- 😀 The video focuses on creating a highly realistic LoRA model of actress Scarlett Johansson using only headshots for training.
- 🔍 When attempting to create half or full body shots with the current LoRA setup, the results may not accurately represent Scarlett Johansson.
- 🚫 The training session with LoRA was conducted using the SD 1.5 model, which limits the flexibility for generating different styles of images.
- 💡 An innovative solution introduced is the 'A Detailer' extension, which allows applying a LoRA model to any photo style by swapping faces.
- 🖼️ The process involves uploading a photo and selecting a base model on the Imageo interface of Automatic1111.
- 🎛️ Skipping the image-to-image step and setting the denoising strength to zero is recommended before proceeding to face swap.
- 🔍 The 'A Detailer' section is expanded to enable face swapping, with options to skip image-to-image and select a face detection model like Face YOLO v8m.
- 🖌️ The 'inpainting' tab allows adjusting the 'inpaint mask blur' for a smooth face blend into the photo.
- ⚙️ The 'use separate checkpoint' option lets users select a different base model for 'A Detailer' to enhance the face swap effect.
- 🔧 The face swap can be fine-tuned by adjusting the denoising strength in 'A Detailer' for optimal results.
- 🎨 'A Detailer' is not limited to image-to-image; it can also be used with text-to-image for a seamless face swap workflow.
Q & A
What was the focus of the last episode in the video series?
-The focus was on creating a super realistic LoRA model of the actress Scarlett Johansson using only headshots for training.
Why does creating half or full body shots with the current LoRA setup pose a challenge?
-Creating half or full body shots is challenging because the LoRA model was trained using headshots, and mixing it with other body parts doesn't produce realistic results that resemble Scarlett Johansson.
What is the solution proposed to overcome the limitations of the current LoRA setup?
-The solution is to use the A Detailer extension, which allows applying the LoRA model to any photo style by isolating and swapping faces.
How does the A Detailer extension work?
-The A Detailer extension works by isolating the face in an image and swapping it with the one generated by LoRA, while keeping the rest of the photo untouched.
What is the first step in using the A Detailer extension as described in the script?
-The first step is to go to the image interface of Automatic1111, upload the photo to work on, and select a base model.
Why is it recommended to set the denoising strength to zero before using A Detailer?
-Setting the denoising strength to zero before using A Detailer is recommended to avoid having to adjust it later in the process, as it speeds up the face swap.
What is the role of the 'Inpainting' tab in the A Detailer extension?
-The 'Inpainting' tab is used to adjust the inpaint mask blur, which helps in blending the swapped face smoothly into the photo without awkward edges.
Why is the 'use separate checkpoint' option important in the A Detailer settings?
-The 'use separate checkpoint' option is important because it allows the use of a different base model for A Detailer, which is necessary if the LoRA model was trained with a different base model.
How can the size of the face box in the original image be adjusted for a better face swap?
-The size of the face box in the original image can be adjusted by opening up the mask pre-processing and using the slider to fine-tune the setting.
Can A Detailer be used with text-to-image generated pictures as well?
-Yes, A Detailer can be used with text-to-image generated pictures, allowing for a face swap after the initial image generation.
Outlines
🖼️ Creating a Realistic AI Model of Scarlett Johansson
The script discusses the process of creating a highly realistic AI model of the actress Scarlett Johansson, focusing on her facial features using headshots for training. The method emphasizes the importance of capturing her unique facial characteristics. However, the script points out the limitations when attempting to create half or full body shots with the same setup, as it doesn't accurately represent Scarlett Johansson. The narrator introduces a solution called the 'a detailer extension,' which allows for the application of the AI model to any photo style, enhancing flexibility in image generation.
