Sampling Step
: 이미지를 향상시키기 위해 샘플링을 몇 번 작동시킬건지 설정하는 탭.
: 수치를 낮게 할수록 속도는 빨라지지만 퀄리티가 떨어질 수 있고, 숫자를 올리면 속도는 느리지만 반대로 퀄리티가 올라간다.
: 숫자를 너무 올리면 이미지가 오히려 망가질수 있다.
Batch Count : 제작할 이미지 갯수를 조절
Batch Size : 한장에 몇개의 이미지를 넣을 것인지 조절
CFG Scale : Prompt 를 얼마나 충실히 적용할 것인지 조절하는 것.
Seed : 하나의 이미지는 고유의 Seed 값을 가진다. 지문과도 같다.
'-1 '를 입력하면 시드를 랜덤하게 만들어준다.
Lora (Low Rank Adaptation)
: CheckPoint(메인 모델)에 변화를 줄 수 있는 보조 모델
: 드림부스를 기반으로 학습된 파일
: 보조 모델이지만 전체 이미지에 큰 영향력을 끼친다.
: 작은 용량, 낮은 GPU 성능 요구
: 동시에 여러 Lora를 적용할 수 있고, 강약 조절도 가능하다.
Embedding
: Texture Inversion
: 메인 모델을 건드리지 않고, 추가적인 효과를 준다.
: 동시에 여러 Embedding 을 적용할 수 있다.
: 다양한 모델에 적용 가능하다.
: 용량이 매우 작다.
: 효과가 적게 나타날 수 있다.
Hyper Network
: Lora 와 Embedding 중간 정도의 영향력을 행사한다.
Vae
: 최종적인 이미지를 조금 다듬어주는 역할을 한다.
설치 방법
Civitai / Model 페이지에 접속한다.
https://civitai.com/models
Filter를 누르면 필요한 모델 타입을 체크하여 골라볼 수 있다.
다운 받은 파일들은 각각 해당하는 폴더에 넣으면 된다.
Lora를 적용하는 방법과 구문 순서는 아래와 같다.
<> 사이에 작성해야 하며, 강도는 0~1까지 원하는 만큼 지정해준다.
0 : 전혀 적용하지 않는다.
1: 완전히 적용한다.
<lora:사용할 로라:강도>
<lora:koreanDollLikeness_v10:0.2>
chilloumix 모델에 아무런 lora를 적용하지 않은 결과물입니다.

여기에 lora 두개를 추가해본다.

lora를 추가함으로써 많은 것이 바뀌었습니다. 하지만 뭔가 어색하다. 그래서 negative Prompt 를 추가한다.

이목구비나 전체적인 이미지가 훨씬 자연스러워졌다.
이제 마지막으로 VAE 를 적용하여 이미지를 개선해보자.
애니 그림체 전용 VAE를 적용했더니 이상하게 나왔다.
실제 사람과 그림을 다르게 인식하는것 같다.
그래서 이번엔 실사 전용 VAE를 적용해보았다.
toneRangeCompressor_trcvae
제대로 나오는 것을 확인할 수 있다.
