### Introduction

This repository contains the original models (AT-net, VG-net) described in the paper [Hierarchical Cross-modal Talking Face Generation with Dynamic Pixel-wise Loss](http://www.cs.rochester.edu/u/lchen63/cvpr2019.pdf). The **demo video** is avaliable at https://youtu.be/eH7h_bDRX2Q. This code can be applied directly in [LRW](http://www.robots.ox.ac.uk/~vgg/data/lip_reading/lrw1.html) and [GRID](http://spandh.dcs.shef.ac.uk/gridcorpus/). The outputs from the model are visualized here: the first one is the synthesized landmark from ATnet, the rest of them are attention, motion map and final results from VGnet.

### Running

0. This code is tested under Python 2.7. The model we provided is trained on LRW. However, it works fine on GRID,VOXCELB and other datasets. You can directly compare this model on other dataset with your own model. We treat this as fair comparison.
0. Pytorch environment:[Pytorch 0.4.1](https://pytorch.org/). (conda install pytorch=0.4.1 torchvision cuda90 -c pytorch)

### Disclaimer and known issues

0. These codes are implmented in Pytorch.
0. In this paper, we train LRW and GRID seperately. 
0. The model are sensitive to input images. Please use the correct preprocessing code.
0. I didn't finish the data processing code yet. I will release it soon. But you can try the model and replace with your own image.
0. If you want to train these models using this version of pytorch without modifications, please notice that:
	- You need at lest 12 GB GPU memory.
	- There might be some other untested issues.
0. There is another intresting and useful research on audio to landmark genration. Please check it out at https://github.com/eeskimez/Talking-Face-Landmarks-from-Speech.
