Global-Flow-Local-Attention

The source code for our paper "Deep Image Spatial Transformation for Person Image Generation" (CVPR2020)

We propose a Global-Flow Local-Attention Model for deep image spatial transformation. Our model can be flexibly applied to tasks such as:

• Pose-Guided Person Image Generation:

• Pose-Guided Person Image Animation

• Face Image Animation

• View Synthesis

News

• 2020.4.30 Several demos are provided for quick exploration.

• 2020.4.29 Code for Pose-Guided Person Image Animation is avaliable now!

• 2020.3.15 We upload the code and trained models of the Face Animation and View Synthesis!

• 2020.3.3 Project Website and Paper are avaliable!

• 2020.2.29 Code for PyTorch is available now!

Colab Demo

For a quick exploration of our model, find the online colab demo.

Get Start

1) Installation

Requirements

• Python 3
• pytorch (1.0.0)
• CUDA
• visdom

Conda installation

# 1. Create a conda virtual environment.
conda create -n gfla python=3.6 -y

3) Pose-Guided Person Image Generation

The Pose-Guided Person Image Generation task is to transfer a source person image to a target pose.

Run the demo of this task:

python demo.py \
--name=pose_fashion_checkpoints \
--model=pose \
--attn_layer=2,3 \
--kernel_size=2=5,3=3 \
--gpu_id=0 \
--dataset_mode=fashion \
--dataroot=./dataset/fashion \
--results_dir=./demo_results/fashion

For more training and testing details, please find the PERSON_IMAGE_GENERATION.md

4) Pose-Guided Person Image Animation

The Pose-Guided Person Image Animation task generates a video clip from a still source image according to a driving target sequence. We further model the temporal consistency for this task.

Run the the demo of this task:

python demo.py \
--name=dance_fashion_checkpoints \
--model=dance \
--attn_layer=2,3 \
--kernel_size=2=5,3=3 \
--gpu_id=0 \
--dataset_mode=dance \
--sub_dataset=fashion \
--dataroot=./dataset/danceFashion \
--results_dir=./demo_results/dance_fashion \
--test_list=val_list.csv

For more training and testing details, please find the PERSON_IMAGE_ANIMATION.md.

5) Face Image Animation

Given an input source image and a guidance video sequence depicting the structure movements, our model generating a video containing the specific movements.

Run the the demo of this task:

python demo.py \
--name=face_checkpoints \
--model=face \
--attn_layer=2,3 \
--kernel_size=2=5,3=3 \
--gpu_id=0 \
--dataset_mode=face \
--dataroot=./dataset/FaceForensics \
--results_dir=./demo_results/face 

We use the real video of the FaceForensics dataset. See FACE_IMAGE_ANIMATION.md for more details.

6) Novel View Synthesis

View synthesis requires generating novel views of objects or scenes based on arbitrary input views.

In this task, we use the car and chair categories of the ShapeNet dataset. See VIEW_SYNTHESIS.md for more details.
