官网：GitHub - roop，参考论文：RobustSwap: A Simple yet Robust Face Swapping Model against Attribute Leakage
面部替换的目标是将源图像的身份（即，面部特征）注入目标图像，同时严格保留与身份无关的目标属性。然而，以前的方法仍然受到源属性泄露的困扰，其中源图像的属性会干扰目标图像的属性。通过分析 StyleGAN 的潜在空间，并且找到适合面部替换任务的潜在组合。因此，开发出简单但稳健的面部替换模型，RobustSwap，对于可能的源属性泄露有抵抗力。此外，利用 3DMM 的隐式和显式信息的协调作为指导，以融入源图像的结构和目标图像的精确姿势。尽管方法仅使用没有身份标签的图像数据集进行训练，但是模型具有生成高保真度和时间一致性视频的能力。通过大量的定性和定量评估，在合成图像和视频方面，与以前的面部替换模型相比，有显著的改进。
1. 测试 SD 模型
模型：墨幽人造人_v1010，使用 LiblibAI 墨幽人造人 官网下载，同时包括 麦橘写实，参考：
wget https://liblibai-online.liblibai.com/web/model/6a226dd292a983b3ed4987402453ad4d954b77825c1cf99d39d8746909791761.safetensors?attname=%E5%A2%A8%E5%B9%BD%E4%BA%BA%E9%80%A0%E4%BA%BA_v1010.safetensors -O 墨幽人造人_v1010.safetensors
wget https://liblibai-online.liblibai.com/web/model/e4a30e4607faeb06b5d590b2ed8e092690c631da0b2becb6224d4bb5327104b7.safetensors?attname=majicMIX%20realistic%20%E9%BA%A6%E6%A9%98%E5%86%99%E5%AE%9E_v6.safetensors -O 麦橘写实_MajicMIX_Realistic_v6.safetensors
LiblibAI 下载速度约 10M / s，非常快。
其他真实系模型包括：MajicMIX、DreamShaper 等。
Embeddings 模型：
- Age Slider，控制年龄，由不同的 Embeddings 控制。
- Gender Slider，控制性别，由不同的 Embeddings 控制。
LoRA 模型：
- Fashion Girl，LoRA，提升真实系模型的人物表现。
2. 安装 Roop 插件

安装 Roop 插件成功，版本 v0.0.2，在下面的插件区域显示，如下：
3. 生成测试图像
正向提示词：
1girl,black footwear,black hair,boots,curtains,dress,floral print,full body,handbag,lips,long hair,long sleeves,looking at viewer,polka dot legwear,shoes,smile,solo,standing,tile floor,tile wall,
a woman standing in front of a building wearing a gray dress and purple socks and a gray jacket with polka dots,Ayami Kojima,long black hair,a hologram,private press,
best quality,masterpiece,ultra high res,(photorealistic:1.4),
负向提示词：
(ng_deepnegative_v1_75t,badhandv4,bad_prompt_version2-neg,EasyNegative:0.9),(worst quality, low quality:1.3),(depth of field, blurry:1.2),(greyscale, monochrome:1.1),croped,lowres,text,jpeg artifacts,(logo,signature,watermark,username,artist name,title:1.3),
注意：提示词来源真实图像反推
After Detailer：
- After Detailer 的脸部提示词，推荐：
detailed face, close-up, portrait, - After Detailer 的手部提示词，推荐：
detailed hand, perfect hand, After Detailer 相关的 ControlNet 模型，推荐 Inpaint 模型，Module 选择 Inpaint_global_harmonious。测试效果不好。
其他配置：
- Upscale:
8x_NMKD-Superscale_150000_G算法，适合真人风格。 - 固定随机种子：

4. 配置与使用 Roop 插件
脸型参考：英国籍亚裔女演员 克拉拉 的图像，头像清晰，即：
调用 Roop 插件生成换脸图像，配置如下：
- 选择
启用 - 调低
面部修复强度至 0.5 - 放大算法，使用现实风格的
8x_NMKD-Superscale； - 模型使用默认的
inswapper_128.onnx，即可 - 注意：放大倍率是2，会导致图像放大 2 倍，即由
1536x2048放大至3072x4096。
即：
需要重新运行之前的配置（或者使用 图生图 功能），再次生成图像，之前的脸部由 AI 生成，现在转换成 克拉拉 图像中的脸型。
