스테이블 디퓨전 기반 정밀 합성 + 해부학적 오류 수정
매 한 줄
"매 anatomy fix 의 본질 은 detection + inpaint 의 loop". 매 SDXL/FLUX base 의 raw output 에서 hand/face/text 의 결함 은 inevitable — 매 ADetailer 의 auto-detect, 매 ControlNet 의 pose/depth lock, 매 second-pass inpaint 가 매 결합되어 production-quality 의 reliable pipeline 의 형성. 매 2026 의 open-source workflow 는 ComfyUI 의 graph + node API 가 standard.
매 핵심
매 problem space
- Hand 의 6-finger / fused digits: SD/SDXL 의 chronic. FLUX.1 dev 에서 의 상당 개선, but 의 not perfect.
- Face degradation at low pixel: 매 small face crop 에서 의 detail loss → ADetailer 가 face crop → high-res inpaint.
- Text 의 illegible: SDXL 의 weak. FLUX 의 strong (그러나 아직 결함 있음).
- Eye 의 asymmetry: gaze direction, pupil size 의 mismatch.
매 도구 (open source)
- ComfyUI: 매 node-based workflow. 매 reproducible JSON.
- A1111 / Forge / reForge: 매 web UI. 매 ADetailer extension 의 default.
- ControlNet: pose/depth/canny/openpose/MediaPipeFace 의 conditioning.
- ADetailer: face/hand 의 auto-detect → inpaint.
- MeshGraphormer / DWPose: 매 hand pose 의 estimation → ControlNet hand_refiner.
- IP-Adapter FaceID Plus v2: 매 face consistency.
매 pipeline 구성
- Base generation (SDXL/FLUX) — high-level composition.
- ADetailer face pass — face crop → upscale → inpaint with same prompt.
- ADetailer hand pass — DWPose 검출 → ControlNet hand_refiner → inpaint.
- Manual touch-up — 잔여 결함 의 mask + inpaint.
- Upscale — Real-ESRGAN / SUPIR / FLUX-Upscale.
매 응용
- Character art (anime, realistic portrait).
- Fashion editorial (pose-precise).
- Comic / manga panel.
- Game asset (consistent character sheets).
💻 패턴
Pattern 1 — ADetailer pipeline (diffusers)
from diffusers import StableDiffusionXLPipeline, StableDiffusionXLInpaintPipeline
from ultralytics import YOLO
import torch
base = StableDiffusionXLPipeline.from_pretrained(
"stabilityai/stable-diffusion-xl-base-1.0", torch_dtype=torch.float16
).to("cuda")
inpaint = StableDiffusionXLInpaintPipeline.from_pretrained(
"diffusers/stable-diffusion-xl-1.0-inpainting-0.1", torch_dtype=torch.float16
).to("cuda")
face_det = YOLO("face_yolov8n.pt")
def adetailer_face(img, prompt):
boxes = face_det(img)[0].boxes.xyxy.cpu().numpy()
for x1,y1,x2,y2 in boxes:
crop = img.crop((x1,y1,x2,y2)).resize((1024,1024))
mask = make_face_mask(crop)
fixed = inpaint(prompt=prompt, image=crop, mask_image=mask,
num_inference_steps=25, strength=0.5).images[0]
img.paste(fixed.resize((int(x2-x1),int(y2-y1))), (int(x1),int(y1)))
return img
Pattern 2 — Hand fix with DWPose + ControlNet
from controlnet_aux import DWposeDetector
from diffusers import StableDiffusionXLControlNetInpaintPipeline, ControlNetModel
dwpose = DWposeDetector.from_pretrained("yzd-v/DWPose")
hand_cn = ControlNetModel.from_pretrained("hr16/ControlNet-HandRefiner-pruned",
torch_dtype=torch.float16)
def fix_hands(img, prompt):
pose = dwpose(img, hand_only=True) # depth-style hand map
mask = hand_mask_from_dwpose(pose)
pipe = StableDiffusionXLControlNetInpaintPipeline.from_pretrained(
"stabilityai/stable-diffusion-xl-base-1.0",
controlnet=hand_cn, torch_dtype=torch.float16
).to("cuda")
return pipe(prompt=prompt, image=img, mask_image=mask,
control_image=pose, num_inference_steps=30,
controlnet_conditioning_scale=0.9).images[0]
Pattern 3 — ControlNet OpenPose lock
from controlnet_aux import OpenposeDetector
from diffusers import StableDiffusionXLControlNetPipeline
op = OpenposeDetector.from_pretrained("lllyasviel/ControlNet")
pose_map = op(reference_image, hand_and_face=True)
cn = ControlNetModel.from_pretrained("xinsir/controlnet-openpose-sdxl-1.0",
torch_dtype=torch.float16)
pipe = StableDiffusionXLControlNetPipeline.from_pretrained(
"stabilityai/stable-diffusion-xl-base-1.0",
controlnet=cn, torch_dtype=torch.float16
).to("cuda")
out = pipe(prompt="cinematic shot of a woman dancing", image=pose_map,
num_inference_steps=30, guidance_scale=6.5).images[0]
Pattern 4 — Multi-ControlNet (depth + canny + pose)
from diffusers import MultiControlNetModel
controlnets = MultiControlNetModel([
ControlNetModel.from_pretrained("xinsir/controlnet-depth-sdxl-1.0", torch_dtype=torch.float16),
ControlNetModel.from_pretrained("xinsir/controlnet-canny-sdxl-1.0", torch_dtype=torch.float16),
ControlNetModel.from_pretrained("xinsir/controlnet-openpose-sdxl-1.0", torch_dtype=torch.float16),
])
result = pipe(prompt=p,
image=[depth_map, canny_map, pose_map],
controlnet_conditioning_scale=[0.6, 0.4, 0.9]).images[0]
Pattern 5 — Differential diffusion (soft mask)
# Soft strength per-pixel mask: 0.0 keep, 1.0 fully regen
import numpy as np
from PIL import Image
def soft_mask(face_box, img_size, edge_blur=24):
m = np.zeros(img_size, dtype=np.float32)
x1,y1,x2,y2 = face_box
m[y1:y2, x1:x2] = 1.0
from scipy.ndimage import gaussian_filter
return Image.fromarray((gaussian_filter(m, edge_blur)*255).astype(np.uint8))
# Pass into pipe.diff_diffusion_strength=
Pattern 6 — Face restore (CodeFormer / GFPGAN)
from codeformer import CodeFormer
cf = CodeFormer(weight_path="codeformer.pth", device="cuda")
restored = cf.enhance(img_np, w=0.7) # 0=keep id, 1=full repair
Pattern 7 — ComfyUI workflow JSON snippet

"inputs": {"steps": 30, "cfg": 6.5, "sampler_name": "dpmpp_2m_sde",

매 결정 기준
| 상황 | Approach |
|---|---|
| Anime portrait, hand 결함 | A1111 + ADetailer (face_yolov8n + hand_yolov8n) |
| Realistic full body | SDXL + Multi-ControlNet (pose+depth) |
| Reproducible production | ComfyUI workflow JSON + Git |
| Maximum quality, slow | FLUX.1 dev + Differential Diffusion |
| Real-time iteration | SDXL Lightning / Turbo |
기본값: 매 SDXL base + ADetailer face/hand pass + 1 manual inpaint round.

- Adjacent: FLUX · ComfyUI · DWPose
🤖 LLM 활용
언제: 매 ComfyUI workflow JSON 의 authoring/debugging, 매 prompt + negative-prompt 의 systematic generation. 언제 X: 매 fine pixel-level inpaint 결정 — 매 visual judgment 가 필요.
❌ 안티패턴
- Single-pass at full res: 매 face/hand 의 detail starvation. 매 second-pass crop+upscale 의 mandatory.
- Wrong ControlNet 조합: 매 pose + canny 동시에 high weight → 매 over-constrain → composition 의 collapse.
- Hand_refiner 없는 SDXL hand: 매 5% 미만 의 success rate.
- ADetailer denoise 1.0: 매 identity 의 destroyed. 매 0.4–0.6 의 sweet spot.
🧪 검증 / 중복
- Verified (Mikubill/sd-webui-controlnet, Bing-su/adetailer; HuggingFace diffusers docs).
- 신뢰도 A.
