# Micro-expression Recognition by Fusing AU Detection and Spatio-temporal Features

## Introduction

This repo contains all the code needed to reproduce the results of this paper - "Micro-expression Recognition by Fusing AU Detection and Spatio-temporal Features" - [[paper]](https://ieeexplore.ieee.org/abstract/document/10446702). It mainly includes two parts of codes, one is Matlab codes, and the other is Python codes.

## Installation for Python

### Requirements

```command
# Install requirement
$ pip install -r requirements.txt

# Download landmarks weight for DLIB
$ mkdir -p PythonCodes/dataloader/weight
$ wget https://github.com/davisking/dlib-models/raw/master/mmod_human_face_detector.dat.bz2 -P dataloader/weight
$ bzip2 -d PythonCodes/dataloader/weight/mmod_human_face_detector.dat.bz2
$ wget https://github.com/davisking/dlib-models/raw/master/shape_predictor_68_face_landmarks.dat.bz2 -P dataloader/weight
$ bzip2 -d PythonCodes/dataloader/weight/shape_predictor_68_face_landmarks.dat.bz2
```

## Instructions for use

In general, this paper conducts end-to-end MER model training on the public datasets, which is divided into the following steps.

1. Video interpolation is performed for each ME sample (with Python codes).
2. Motion magnification on interpolated frames (with Matlab codes).
3. Optical flow extraction between amplified motion differences (with Matlab codes).
4. Preprocessing (with Python codes): Extract a specified number of ROIs for the optical flow map; and process the original ME sample, convert it to the corresponding data format for subsequent AU detection.
5. End-to-end training is based on the above ROIs data and AU data (with Python codes).

Since there are many data files involved, the data path needs to be carefully modified according to the comments.

## DLIB with GPU (not necessary)

```shell
# Remove the cpu version first
$ pip uninstall dlib
# Install cudnn and its toolkit
$ conda install cudnn cudatoolkit
# Build from source
$ git clone https://github.com/davisking/dlib.git
$ cd dlib
$ mkdir build & cd build
$ cmake .. \
    -DDLIB_USE_CUDA=1 \
    -DUSE_AVX_INSTRUCTIONS=1 \
    -DCMAKE_PREFIX_PATH=<path to  conda env>\
    -DCMAKE_C_COMPILER=gcc-6 -DCMAKE_CXX_COMPILER=g++-6
$ cmake --build .
$ cd ..
$ python setup.py install \
    --set USE_AVX_INSTRUCTIONS=1 \
    --set DLIB_USE_CUDA=1 \
    --set CMAKE_PREFIX_PATH=<path to  conda env>  \
    --set CMAKE_C_COMPILER=gcc-6 \
    --set CMAKE_CXX_COMPILER=g++-
```

## Pretrained models

### RIFE

The [RIFE](https://github.com/hzwer/ECCV2022-RIFE) (Real-time Intermediate Flow Estimation) model is used in the video interpolation step, and the required model is included in this repo due to its small size.

### MagNet

The structure of MagNet was adapted from [here](https://github.com/ZhengPeng7/motion_magnification_learning-based). Download the pra-trained models, place it in the appropriate directory, and modify the path in `generate_MagNet_images.py` to use it for data preprocessing.
