## Introduction |
|
|
|
An experimental version of IP-Adapter-FaceID: we use face ID embedding from a face recognition model instead of CLIP image embedding, additionally, we use LoRA to improve ID consistency. IP-Adapter-FaceID can generate various style images conditioned on a face with only text prompts. |

|
**Update 2023/12/27**: |
|
|
|
IP-Adapter-FaceID-Plus: face ID embedding (for face ID) + CLIP image embedding (for face structure) |

**Update 2023/12/28**: |
|
|
|
IP-Adapter-FaceID-PlusV2: face ID embedding (for face ID) + controllable CLIP image embedding (for face structure) |
|
|
|
You can adjust the weight of the face structure to get different generation! |

## Usage |
|
|
|
### IP-Adapter-FaceID |
|
|
|
Firstly, you should use [insightface](https://github.com/deepinsight/insightface) to extract face ID embedding: |
|
|
|
```python |
|
|
|
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) |
|
``` |
|
|
|
Then, you can generate images conditioned on the face embeddings: |
|
|
|
```python |
|
|
|
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 |
|
) |
|
|
|
``` |
|
|
|
### IP-Adapter-FaceID-SDXL |
|
|
|
Firstly, you should use [insightface](https://github.com/deepinsight/insightface) to extract face ID embedding: |
|
|
|
```python |
|
|
|
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) |
|
``` |
|
|
|
Then, you can generate images conditioned on the face embeddings: |
|
|
|
```python |
|
|
|
import torch |
|
from diffusers import StableDiffusionXLPipeline, DDIMScheduler |
|
from PIL import Image |
|
|
|
from ip_adapter.ip_adapter_faceid import IPAdapterFaceIDXL |
|
|
|
base_model_path = "SG161222/RealVisXL_V3.0" |
|
ip_ckpt = "ip-adapter-faceid_sdxl.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, |
|
) |
|
pipe = StableDiffusionXLPipeline.from_pretrained( |
|
base_model_path, |
|
torch_dtype=torch.float16, |
|
scheduler=noise_scheduler, |
|
add_watermarker=False, |
|
) |
|
|
|
# load ip-adapter |
|
ip_model = IPAdapterFaceIDXL(pipe, ip_ckpt, device) |
|
|
|
# generate image |
|
prompt = "A closeup shot of a beautiful Asian teenage girl in a white dress wearing small silver earrings in the garden, under the soft morning light" |
|
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=2, |
|
width=1024, height=1024, |
|
num_inference_steps=30, guidance_scale=7.5, seed=2023 |
|
) |
|
|
|
``` |
|
|
|
### IP-Adapter-FaceID-Plus |
|
|
|
Firstly, you should use [insightface](https://github.com/deepinsight/insightface) to extract face ID embedding and face image: |
|
|
|
```python |
|
|
|
import cv2 |
|
from insightface.app import FaceAnalysis |
|
from insightface.utils import face_align |
|
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) |
|
face_image = face_align.norm_crop(image, landmark=faces[0].kps, image_size=224) # you can also segment the face |
|
``` |
|
|
|
Then, you can generate images conditioned on the face embeddings: |
|
|
|
```python |
|
|
|
import torch |
|
from diffusers import StableDiffusionPipeline, DDIMScheduler, AutoencoderKL |
|
from PIL import Image |
|
|
|
from ip_adapter.ip_adapter_faceid import IPAdapterFaceIDPlus |
|
|
|
v2 = False |
|
base_model_path = "SG161222/Realistic_Vision_V4.0_noVAE" |
|
vae_model_path = "stabilityai/sd-vae-ft-mse" |
|
image_encoder_path = "laion/CLIP-ViT-H-14-laion2B-s32B-b79K" |
|
ip_ckpt = "ip-adapter-faceid-plus_sd15.bin" if not v2 else "ip-adapter-faceid-plusv2_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 = IPAdapterFaceIDPlus(pipe, image_encoder_path, 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, face_image=face_image, faceid_embeds=faceid_embeds, shortcut=v2, s_scale=1.0, |
|
num_samples=4, width=512, height=768, num_inference_steps=30, seed=2023 |
|
) |
|
|
|
``` |
|
|
|
|
|
## Limitations and Bias |
|
- The model does not achieve perfect photorealism and ID consistency. |
|
- The generalization of the model is limited due to limitations of the training data, base model and face recognition model. |
