MTCNN For Android Java
This project is the Android implementaion of MTCNN face detection. I use the pretrained model in Google's Facenet project and transfrom the the .npy files into one .pb file first.

  • IDE:Android Studio3.1.2
  • Core Class MTCNN (see file MTCNN.Java)
    • Get Instance : MTCNN mtcnn=new MTCNN(getAssets())
    • It is easy to use ,here is the core API:
      • public Vector detectFaces(Bitmap bitmap,int minFaceSize)
        • [parameter] bitmap : Image to process
        • [parameter] minFaceSize: minimum face size in pixels.(The speed will be faster when minFaceSize is bigger)
        • [Return Value]: Position of All faces(And their correspoinding facial landmarks(2mouse+1nose+2*eyes).

MTCNN For Android Java
主要参考MTCNN论文和Facenet中MTCNN的实现,纯Java实现。为了方便java调用,我先把npy转为pb。

  • 编译环境:Android Studio3.1.2
  • 核心类MTCNN用法 (MTCNN.Java)
    • 类实例化 MTCNN mtcnn=new MTCNN(getAssets())
    • 只有1个API:public Vector detectFaces(Bitmap bitmap,int minFaceSize)
      • 参数bitmap:要处理的图片
      • 参数minFaceSize:最小的脸像素值,一般>=40。越大则检测速度越快,但会忽略掉较小的脸
      • 返回值:所有的脸的Box,包括left/right/top/bottom/landmark(一共5个点,嘴巴鼻子眼)
