How to Use

Labeller

prepare your dataset by manually labeling the segmentation mask. You might need a few, 2~3 train data

Few-shot Train

FewShotCNN.pt 생성

python train_fewshot.py --config_path './auto_shot.yaml'

Few-shot Test

1.projector.py에서 원하는 이미지의 latent vector추출 2.fewshot CNN에 넣음

python test_fewshot.py --config auto_shot.yaml

Auto-shot Train

FewShotCNN에서 생성 + labeling한 dataset으로 UNET 훈련

python train_autoshot.py --config_path './auto_shot.yaml'

create_dataset

data creation for auto_shot segmentation 5 example data given

python create_dataset.py --config_path 'auto_shot.yaml'
