Overview

Dependencies and Installation

1. Clone Repo

   git clone https://github.com/sczhou/ProPainter.git

2. Create Conda Environment and Install Dependencies

   conda env create -f environment.yaml
   conda activate propainter

   • Python >= 3.7
   • PyTorch >= 1.6.0
   • CUDA >= 9.2
   • mmcv-full (refer the command table to install v1.4.8)

Get Started

Prepare pretrained models

Download our pretrained models from Releases V0.1.0 to the weights folder. (All pretrained models can also be automatically downloaded during the first inference.)

The directory structure will be arranged as:

weights
   |- ProPainter.pth
   |- recurrent_flow_completion.pth
   |- raft-things.pth
   |- i3d_rgb_imagenet.pt (for evaluating VFID metric)
   |- README.md

Quick test

We provide some examples in the inputs folder. Run the following commands to try it out:

# The first example (object removal)
python inference_propainter.py --video inputs/object_removal/bmx-trees --mask inputs/object_removal/bmx-trees_mask 
# The second example (watermark removal)
python inference_propainter.py --video inputs/watermark_removal/running_car.mp4 --mask inputs/watermark_removal/mask.png

The results will be saved in the results folder. To test your own videos, please prepare the input mp4 video (or split frames) and frame-wise mask(s).

If you want to specify the video resolution for processing or avoid running out of memory, you can use the --set_size flag and set the video size of --width and --height:

# process a 576x320 video
python inference_propainter.py --video inputs/watermark_removal/running_car.mp4 --mask inputs/watermark_removal/mask.png --set_size --height 320 --width 576 

Regarding the issue of running out of memory, you can mitigate it by reducing the number of local neighbors through decreasing the --neighbor_length (default 20) or reducing the number of global references by increasing the --ref_stride (default 10).

Dataset preparation for training and evaluation

The training and test split files are provided in datasets/<dataset_name>. For each dataset, you should place JPEGImages to datasets/<dataset_name>. Resize all video frames to size 432x240 for training. Unzip downloaded mask files to datasets.

The datasets directory structure will be arranged as: (Note: please check it carefully)

datasets
   |- davis
      |- JPEGImages_432_240
         |- <video_name>
            |- 00000.jpg
            |- 00001.jpg
      |- test_masks
         |- <video_name>
            |- 00000.png
            |- 00001.png   
      |- train.json
      |- test.json
   |- youtube-vos
      |- JPEGImages_432_240
         |- <video_name>
            |- 00000.jpg
            |- 00001.jpg
      |- test_masks
         |- <video_name>
            |- 00000.png
            |- 00001.png
      |- train.json
      |- test.json   

Evaluation

Run one of the following commands for evaluation:

 # For evaluating flow completion model
 python scripts/evaluate_flow_completion.py --dataset <dataset_name> --video_root <video_root> --mask_root <mask_root> --save_results
 # For evaluating ProPainter model
 python scripts/evaluate_propainter.py --dataset <dataset_name> --video_root <video_root> --mask_root <mask_root> --save_results

The scores and results will also be saved in the results_eval folder. Please --save_results for further evaluating temporal warping error.

Training

Our training configures are provided in train_flowcomp.json (for Recurrent Flow Completion Network) and train_propainter.json (for ProPainter).

Run one of the following commands for training:

 # For training Recurrent Flow Completion Network
 python train.py -c configs/train_flowcomp.json
 # For training ProPainter
 python train.py -c configs/train_propainter.json

You can run the same command to resume your training.
