人脸活体检测

活体检测代码是基于面部光流特征和面部68个关键点的数学特征,使用了四层验证关卡来保证登录用户的活体性。最后,用户的三张正脸的活体照片将被保存下来上传到人脸验证服务器用于验证人脸的合法性。

活体检测是基于下面两个开源工具。其中,OpenFace的CLNF算法用于人脸关键点匹配,SeetaFace进行更为实时的人脸检测和跟踪

活体验证关卡包括:

  • 基于面部材质的光流特征
  • 基于面部旋转时关键点的欧氏距离特征
  • 基于活体的嘴部可动性特征
  • 基于活体的眼部可动性特征

安装

MAC

准备

  • 首先安装Homebrew,homebrew是类似于Linux系统上apt-get的软件。

  • 安装TBB,OpenCV3(必须3及以上版本)和 boost

    brew install boost tbb opencv3

Build

在命令行执行下列指令:

mkdir build
cd build 
cmake -D CMAKE_BUILD_TYPE=RELEASE ..
make

测试

进入到build/bin目录下。执行

./FaceLivenessDetection

Ubuntu 14.0

sudo apt-get update

sudo apt-get install build-essential

Cmake:

sudo apt-get install cmake

Get BLAS (for dlib)

sudo apt-get install libopenblas-dev liblapack-dev
