erAIser

‘erAIser’ is a service that provides a specific object erased video by using video object segmentation and video inpainting methods.

Most of video inpainting model need segmentation mask of objects. But it is hard to get in normal way. For your convenience, we used a deep learning model that allows users to easily obtain segmentation masks. We combined this video object segmentation model with the video inpainting model to increase usability. Additionally, we use AANet to change object to other object in object erased video.

Our team consists of nine members of ‘Tobigs’ who are interested in computer vision task.

All you have to do is draw the object bounding box that you want to erase in the first frame. Then 'erAIser' will make a video of the object being erased. Let’s make your own video of a specific object being erased with ‘erAIser’!

You can look around our web at the following link. For your information, the model is currently not working on the web due to the GPU environment.

Usage

Environment Setup

This code was tested in the following environments

• Ubuntu 18.04.5
• Python 3.7
• Pytorch 1.8.1
• CUDA 9.0
• GCC 5.5 (gnu c++14 compiler)

If you don't use gnu c++14 compiler, then you will encounter CUDA build error

1. Clone the repository & Setup

git clone https://github.com/shkim960520/tobigs-image-conference.git
cd tobigs-image-conference
conda create -n erAIser python=3.7 -y
conda activate erAIser
conda install cudatoolkit=9.0 -c pytorch -y
pip install -r requirements.txt
bash install.sh

2. Setup python path

export PYTHONPATH=$PWD:$PYTHONPATH
cd vos/
export PYTHONPATH=$PWD:$PYTHONPATH
cd ../vi/
export PYTHONPATH=$PWD:$PYTHONPATH
cd ../web/
export PYTHONPATH=$PWD:$PYTHONPATH
cd ../AANet/
export PYTHONPATH=$PWD:$PYTHONPATH
cd ../

Demo

1. Setup your environment
2. Download the Deep Video Inpainting model

cd vi/results/vinet_agg_rec

file_id="1_v0MBUjWFLD28oMfsG6YwG_UFKmgZ8_7"
file_name="save_agg_rec_512.pth"
curl -sc /tmp/cookie "https://drive.google.com/uc?export=download&id=${file_id}" > /dev/null
code="$(awk '/_warning_/ {print $NF}' /tmp/cookie)"
curl -Lb /tmp/cookie "https://drive.google.com/uc?export=download&confirm=${code}&id=${file_id}" -o ${file_name}

file_id="12TRCSwixAo9AqyZ0zXufNKhxuHJWG-RV"
file_name="save_agg_rec.pth"
curl -sc /tmp/cookie "https://drive.google.com/uc?export=download&id=${file_id}" > /dev/null
code="$(awk '/_warning_/ {print $NF}' /tmp/cookie)"
curl -Lb /tmp/cookie "https://drive.google.com/uc?export=download&confirm=${code}&id=${file_id}" -o ${file_name}

cd ../../../

3. Download the Siammask model

wget http://www.robots.ox.ac.uk/~qwang/SiamMask_DAVIS.pth

file_id="1IKZWpMeWXq-9osBqG7e7bTABumIZ32gB"
file_name="checkpoint_e19.pth"
curl -sc /tmp/cookie "https://drive.google.com/uc?export=download&id=${file_id}" > /dev/null
code="$(awk '/_warning_/ {print $NF}' /tmp/cookie)"
curl -Lb /tmp/cookie "https://drive.google.com/uc?export=download&confirm=${code}&id=${file_id}" -o ${file_name}

4. Download the AANet model

cd AANet/
mkdir checkpoints
cd checkpoints/

file_id="1DT6_SZHTkmuEWvCfs07F2mGLSkgxYplo"
file_name="4dataset384.pth"
curl -sc /tmp/cookie "https://drive.google.com/uc?export=download&id=${file_id}" > /dev/null
code="$(awk '/_warning_/ {print $NF}' /tmp/cookie)"
curl -Lb /tmp/cookie "https://drive.google.com/uc?export=download&confirm=${code}&id=${file_id}" -o ${file_name}

cd ../../

5. Make results directory for saving result video

mkdir results

results is defualt setting. You can change this.

6-1. Run inference.py for erasing

python3 inference.py --resume checkpoint_e19.pth --config config_inference.json

6-2. Run inference.py for change object to other (ex. person, animation character)

python3 inference.py --resume SiamMask_DAVIS.pth --config config_inference.json --using_aanet True

The result video will be saved in results.
