Input 바꿔보기:

  • 현재: LAB pretrained VGG19 에 reference, target 이 LLL 들어감
  • LAB pretrained VGG19 에 reference 는 LAB, target 은 L00

Gradient update 하게 해주기:

  • 현재: frozen
  • unfreeze 해서 gradient 가 흐르게 하기. 이때 checkpoint 에 save / load 할때도 같이 읽어오게 하기

첫 시도:

  • Ref용 vgg는 그냥 rgb pretrained vgg
  • Target용 vgg는 rgb pretrained를 grayscale 로 transfer learning
  • 둘다 freeze

L fine-tuned VGG는 어느 정도 Train이 되었음 (49 epoch, val : Top-1 6970 % / Top-5 8990 %).
이에 vgg_change branch에서 VGG 변경 작업 진행 및 완료
현재는 둘다 freeze 된 상태임 (requires_grad = False)

LAB 읽는 방식 바꾸기 전

warped image 는 괜찮게 나오지만 오히려 synthesized image 가 엄청 안나옴. gamma, beta 값을 뜯어보고 디버깅을 진행해야할듯.

이 이슈를 진행:

LAB 읽는 방식 바꾼 후 + 새로운 VGG
