Inpaint
Inpainting is a way of fixing parts of an image that are missing or damaged. For example, if you have a picture of a person with a hole in their shirt, you can use inpainting to fill in the hole with the same color and texture as the rest of the shirt. Inpainting can also be used to remove unwanted objects from an image, like a trash can or a photobomber. You can use the text prompt to specify what you want to be in the masked area.
Stable Diffusion's inpainting uses heat to smooth out the image. Imagine you have a metal plate with some holes in it, and you heat it up until it becomes soft and bendy. Then you can press the plate flat and the holes will disappear. That's kind of how Stable Diffusion works, but with pixels instead of metal. It makes the pixels near the missing or damaged area spread out and fill in the gaps, creating a natural-looking patch.
To use Stable Diffusion inpainting, you need to have an image that you want to fix, and a mask that shows which parts of the image are missing or damaged. The mask is usually a black and white image, where black means the pixel is good and white means the pixel is bad. Then you can use a program like Stable Diffusion GUI or Dreambooth to apply the inpainting process to your image and mask. You can also adjust some settings like the temperature, the number of steps, and the style to change how the inpainting looks.
