顔認識API

Java Androidを使用して、写真を与えられたカメラで顔の認識を行う方法を見つけようとしています。

何か案は？ APIの提案はありますか？

Microsoft Face APIを試すことができます。人を検出して識別することができます。フェイスAPIの詳細 こちら 。

macgyver は、使いやすいAPIを介して顔検出プログラムを提供します。

以下のプログラムは、パブリックイメージへの参照を取得し、イメージで検出された顔の座標と寸法の配列を返します。

このコードを使用

public class MainActivity extends AppCompatActivity { 

private FaceOverlayView mFaceOverlayView;

@Override 
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mFaceOverlayView = (FaceOverlayView) findViewById( R.id.face_overlay );

    InputStream stream = getResources().openRawResource( R.raw.face );
    Bitmap bitmap = BitmapFactory.decodeStream(stream);

    mFaceOverlayView.setBitmap(bitmap);

} }
