Denoising strength determines how much noise is added to an image before the sampling steps. It is a common setting in image-to-image applications in Stable Diffusion.
The value of denoising strength ranges from 0 to 1. 0 means no noise is added to the input image. 1 means the input image is completely replaced with noise.
You can understand denoising strength as the balance between preserving the original image and creating a completely new image.
The higher the denoising strength, the more the image will change. (View Highlight)
You should not set the denoising strength too high in inpainting. Otherwise, the generation will be incoherent to the rest of the image.
There are ways to use a high denoising strength in inpainting:
• Use an inpainting checkpoint model.
• Use ControlNet.
See the inpainting tutorial for details. (View Highlight)
