MTCNN For Android Java
This project is the Android implementation 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)
