https://stable-diffusion-art.com/inpainting_basics/icon-default.png?t=N3I4https://stable-diffusion-art.com/inpainting_basics/inpainting的应用主要是重绘,目前的模型换衣主要还是通过lora训练特定衣服来实现的。

模型权重:

!wget https://huggingface.co/runwayml/stable-diffusion-inpainting/resolve/main/sd-v1-5-inpainting.ckpt -O models/Stable-diffusion/sd-v1-5-inpainting.ckpt

v1.5的效果确实要比v1.4要好。

[emma watson: amber heard: 0.5], (long hair:0.5), headLeaf, wearing stola, vast roman palace, large window, medieval renaissance palace, ((large room)), 4k, arstation, intricate, elegant, highly detailed.

prompt:

复用原始的prompt,像限定区域的图像生成

image size:

与原图保持一致

face restoration:

可以打开上面的restore faces,并且在设置中设计codeformer,这是人脸恢复模型。

mask content:

如果希望和原始图片的颜色形状保持一致,就选original,inpainting face常选original,一般使用original和denoising strength能够实现不同的效果。如果想生成与原来完全不同的东西,移除或者隐藏手臂之类的,可以使用latent noise/latent nothing.

  • Fill: Initialize with a highly blurred of the original image.
  • Original: Unmodified.
  • Latent noise: Masked area initialized with fill and random noise is added to the latent space.
  • Latent nothing: Like latent noise except no noise is added to the latent space.

denosing strength:

去噪强度表明和原始图像之间的变化,为0时,不会改变,为1时,将得到一张不相关的修复,0.75通常是不错的值。

sampling steps:20

sampling method:euler a

cfg(classifer free guidace scale):

1 – Mostly ignore your prompt.
3 – Be more creative.
7 – A good balance between following the prompt and freedom.
15 – Adhere more to the prompt.
30 – Strictly follow the prompt.

tips for inpainting:

1.一次一个小区域

2.将masked content设置为original,并且调整denoising strength

3.可以用使用ps等软件绘制mask
