OpenFaceAnalyzer

This file can be used to analyze multiple videos in a specified root directory using the OpenFace software. The output is saved in an organized manner in a specified directory.

Prerequisites

• Windows
• Python 3
• OpenFace should be downloaded and installed according to the installation wiki of OpenFace

Usage

1. Download run_open_face.py
2. Specify the root directory where all videos that should be analyzed are located using -root [rootdir]. This can either be a folder containing just videos, or a folder with subdirectories containing the videos.
3. Specify where FeatureExtraction.exe from OpenFace is located using -open [path]
4. Specify where the output should be saved using -out [output directory]
5. Use the optional parameter -suf [suffix] to specify which files will be analyzed. Example: with -suf face.mpg only files that end with face.mpg are analyzed. If this parameter is omitted all files in rootdir are analyzed.

Example:

python C:\Downloads\run_open_face.py -root C:\workspaces\videos -open C:\OpenFace\OpenFace_2.0.5_win_x64\FeatureExtraction.exe -out C:\OpenFace\Output -suf face.mpg

Output

For every video that is analyzed a folder is created in the specified output directory containing the outputs from the OpenFace software.
