Video Harmonization with Triplet Spatio-Temporal Variation Patterns

Here we provide the PyTorch implementation and pre-trained model of our latest version.

Prerequisites

• Linux
• Python 3
• CPU or NVIDIA GPU + CUDA CuDNN

Video Harmonization

Train/Test

• Download HYouTube dataset.

• Train our VTT model:

CUDA_VISIBLE_DEVICES=0 python train.py --model basestv2 --netG vth --name experiment_name --deformable_depth x --gpt_depth x --dataset_root <dataset_dir> --batch_size x --init_port xxxx --loss_T --save_iter_model

• Test our VTT model:

CUDA_VISIBLE_DEVICES=0 python test.py --model basestv2 --netG  vth  --name experiment_name --deformable_depth x --gpt_depth x --dataset_root <dataset_dir> --batch_size 1  --init_port xxxx

Apply a pre-trained model

• Download pre-trained models from BaiduCloud (access code: h63l), and put latest_net_G.pth in the directory checkpoints/vth_harmonization. Run:

CUDA_VISIBLE_DEVICES=0 python test.py --model basestv2 --netG  vth  --name vth_harmonization --deformable_depth 2 --gpt_depth 2 --dataset_root <dataset_dir> --batch_size 1  --init_port xxxx

Evaluation

To evaluate the spatial consistency, run:

CUDA_VISIBLE_DEVICES=0 python evaluation/ih_evaluation.py --dataroot <dataset_dir> --result_root results/experiment_name/test_latest/images/ --evaluation_type hyt --dataset_name HYT

To evaluate the temporal consistency, run:

python tc_evaluation.py --dataset_root <dataset_dir> --experiment_name experiment_name --mode 'v' --brightness_region 'foreground'

Real composite image harmonization

More compared results can be found at BaduCloud (access code: h63l).
