IP-Adapter-FaceID Model SD-SDXL，IPAdapter-FaceID 模型库

IPAdapter FaceID 的实验版本：我们使用来自人脸识别模型的人脸 ID 嵌入而不是 CLIP 图像嵌入，此外，我们使用 LoRA 来提高 ID 一致性。

IP Adapter FaceID 可以生成以面部为条件的各种样式图像，只需文本提示。

最近更新 ：

IP-Adapter-FaceID-Plus：人脸ID嵌入（用于人脸ID）+CLIP图像嵌入（用于人脸结构）

更新：

IP-Adapter-FaceID-PlusV2：人脸ID嵌入（用于人脸ID）+可控CLIP图像嵌入（用于人脸结构）

您可以调整面部结构的重量以获得不同的世代！

更新：

IP-Adapter-FaceID-SDXL：IP-Adapter-FaceID 的实验性 SDXL 版本

更新：

IP-Adapter-FaceID-PlusV2-SDXL：IP-Adapter-FaceID-PlusV2 的实验性 SDXL 版本

更新：

IP-Adapter-FaceID-Portrait：与 IP-Adapter-FaceID 相同，但用于肖像生成（没有 lora！没有 controlnet！具体来说，它接受多个面部图像以增强相似度（默认值为 5）。

用法简介

IP 适配器 FaceID

首先，您应该使用 insightface 来提取人脸 ID 嵌入：

import cv2
from insightface.app import FaceAnalysis
import torch

app = FaceAnalysis(name="buffalo_l", providers=['CUDAExecutionProvider', 'CPUExecutionProvider'])
app.prepare(ctx_id=0, det_size=(640, 640))

image = cv2.imread("person.jpg")
faces = app.get(image)

faceid_embeds = torch.from_numpy(faces[0].normed_embedding).unsqueeze(0)

然后，您可以生成以人脸嵌入为条件的图像：

import torch
from diffusers import StableDiffusionPipeline, DDIMScheduler, AutoencoderKL
from PIL import Image

from ip_adapter.ip_adapter_faceid import IPAdapterFaceID

base_model_path = "SG161222/Realistic_Vision_V4.0_noVAE"
vae_model_path = "stabilityai/sd-vae-ft-mse"
ip_ckpt = "ip-adapter-faceid_sd15.bin"
device = "cuda"

noise_scheduler = DDIMScheduler(
    num_train_timesteps=1000,
    beta_start=0.00085,
    beta_end=0.012,
    beta_schedule="scaled_linear",
    clip_sample=False,
    set_alpha_to_one=False,
    steps_offset=1,
)
vae = AutoencoderKL.from_pretrained(vae_model_path).to(dtype=torch.float16)
pipe = StableDiffusionPipeline.from_pretrained(
    base_model_path,
    torch_dtype=torch.float16,
    scheduler=noise_scheduler,
    vae=vae,
    feature_extractor=None,
    safety_checker=None
)

# load ip-adapter
ip_model = IPAdapterFaceID(pipe, ip_ckpt, device)

# generate image
prompt = "photo of a woman in red dress in a garden"
negative_prompt = "monochrome, lowres, bad anatomy, worst quality, low quality, blurry"

images = ip_model.generate(
    prompt=prompt, negative_prompt=negative_prompt, faceid_embeds=faceid_embeds, num_samples=4, width=512, height=768, num_inference_steps=30, seed=2023
)

您也可以使用普通的 IP 适配器和普通的 LoRA 来加载模型：

import torch
from diffusers import StableDiffusionPipeline, DDIMScheduler, AutoencoderKL
from PIL import Image

from ip_adapter.ip_adapter_faceid_separate import IPAdapterFaceID

base_model_path = "SG161222/Realistic_Vision_V4.0_noVAE"
vae_model_path = "stabilityai/sd-vae-ft-mse"
ip_ckpt = "ip-adapter-faceid_sd15.bin"
lora_ckpt = "ip-adapter-faceid_sd15_lora.safetensors"
device = "cuda"

noise_scheduler = DDIMScheduler(
    num_train_timesteps=1000,
    beta_start=0.00085,
    beta_end=0.012,
    beta_schedule="scaled_linear",
    clip_sample=False,
    set_alpha_to_one=False,
    steps_offset=1,
)
vae = AutoencoderKL.from_pretrained(vae_model_path).to(dtype=torch.float16)
pipe = StableDiffusionPipeline.from_pretrained(
    base_model_path,
    torch_dtype=torch.float16,
    scheduler=noise_scheduler,
    vae=vae,
    feature_extractor=None,
    safety_checker=None
)

# load lora and fuse
pipe.load_lora_weights(lora_ckpt)
pipe.fuse_lora()

# load ip-adapter
ip_model = IPAdapterFaceID(pipe, ip_ckpt, device)

# generate image
prompt = "photo of a woman in red dress in a garden"
negative_prompt = "monochrome, lowres, bad anatomy, worst quality, low quality, blurry"

images = ip_model.generate(
    prompt=prompt, negative_prompt=negative_prompt, faceid_embeds=faceid_embeds, num_samples=4, width=512, height=768, num_inference_steps=30, seed=2023
)

faceid_embeds = torch.from_numpy(faces[0].normed_embedding).unsqueeze(0)
face_image = face_align.norm_crop(image, landmark=faces[0].kps, image_size=224) # you can also segment the face

局限性和偏见

• 这些模型没有实现完美的照片级真实感和 ID 一致性。
• 由于训练数据、基础模型和人脸识别模型的限制，模型的泛化受到限制。

非商业用途

AS InsightFace预训练模型可用于非商业研究目的，IP-Adapter-FaceID模型仅用于研究目的，不用于商业用途。
