Notation 정의

Content image > $C$

• Content image Luminance channel(Y channel) > $Y_C$
• Content image color channel(IQ channel) > $IQ_{C}$

Texture image > $S_t$

• Texture image Luminance channel (Y channel) > $Y_{S_t}$
• Texture image color channel (IQ channel) > $IQ_{S_t}$

Color image > $S_c$

• Color image Luminance channel(Y channel) > $Y_{S{c}}$
• Color image color channel(IQ channel) > $IQ_{S_{C}}$

Color tansfer를 어떻게 할 것이냐

1. Luminace only transfer
   • Y channel에서만 style transfer
2. Color historgram matching
   • color historgram matching 후 style transfer

문제점

• luminace only transfer > color imagecolor의 spatial 정보가 유지됨

해결 방법 제안

1. Luminacne only (Adain) 방식 사용해보기 > 태헌, 정빈

   • VGG(RGB) > Y image를 받았을때 style을 잘 꺼내냐?

2. luminance only space+color transfer (Adain) 방식 사용하기

   • $S_t$와 $C$로부터 luminance channel(Y channel) $Y_{S_t}, Y_C$ 계산
   • $Y_{S_t}, Y_C$를 이용하여 style transfer 진행, $\hat{Y}$계산
   • $S_c$와 $C$로부터 color channel(IQ channel) $IQ_{S_C}, IQ_C$ 계산
   • $IQ_{S_C}, IQ_C$를 이용하여 style transfer 진행, $\hat{IQ}$ 계산
   • $\hat{Y}$와 $\hat{IQ}$를 합쳐서 target image 생성

3. Color histogram matching 방식 사용 > 건하, 원준
