FaceDemo: a simple 3D face alignment and warping demo

Input: face image/video

Output: Textured 3D face model

Overview

This is the author's implementation of 3D face alignment and warping method described in:

In ACM Transactions on Graphics (Proceedings of SIGGRAPH Asia 2014)

Please cite our paper if you use our code for your research.

Given an image or a video sequence that contains a face, the program can align and warp the face to a 3D face model. The user can further rotate/translate the face, and adjust the camera projection (perspective projection or orthogonal projection). The program also provides different OpenGL rendering options. See "Usage" for details.

Requirements

  • OpenCV:
sudo apt-get install libopencv-dev
  • OpenGL and GLUT:
sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev
sudo apt-get install libxmu-dev libxi-dev
  • CLM Tracker by Jason Saragih (included)

Getting Started (Linux)

  • Download and unzip the code.

  • Run the following command.

mkdir cbuild
cd cbuild
cmake -DCMAKE_BUILD_TYPE=Release  ../
make

Usage

  1. Command line interface: ./FaceDemo mode filePath
    • Example (image): ./FaceDemo image ./data/bush.jpg
    • Example (video): ./FaceDemo video ./data/eli.avi
  2. The program displays three windows:
  • The "Detected Points" window shows the original input frame with the detected feature points.
  • The "3D Face" window shows a 3D face model rendered by OpenGL.
  • The "Projected Face" window shows a 2D projection result of the 3D face model. The program projects the 3D face back to the original image.
  1. User Interaction: "3D Face" window takes the user's keyboard input.
    • shift + arrow keys: translate the face.
    • arrow keys: rotate the face.
    • +/-: zoom in/out
    • p: toggle between a perspective projection and an orthogonal projection.
    • s: toggle between flat and smooth shading.
    • w: toggle between filled and wireframe mode.
    • t: toggle between static mode and transformation mode: for static mode, the 3D face model doesn't rotate and translate.
    • q: quit the program
